Can't access specific website

I've been trying to access a specific website – http://www.statcounter.com/ – for the last few days, but all I get is a blank, white page. I know the site is working and it's just a problem with my Mac. I've been searching the net for a solution and for PCs it seems to involve doing something to the TCP/IP, but I can't figure out what needs to be done in Macs. Any suggestions? Thanks
I should add that my internet connection is via airport.

I notice that your OS is 10.3.2. I'm not sure what further free updates are available from Apple but I would apply these as they might fix your problem. Better still would be to upgrade to at least Tiger if you can afford it. I had no problem from my MBP getting to the website.
It's possible that your eMac is having trouble with the drawing of the web page from this site which might use a more complex web page structure. I think this can be an issue on older machines occasionally.

Can't access specific website to update

really hope someone can help me with this. I am trying to update a website that my company manages, but for some reason, my computer is the only one that cannot access this website. Whenever I try, I get "could not be found" or "connection was refused." I cannot upload to this website for the same reasons. It is not the browser because the same message appears in Safari, Explorer and Firefox.
I have emptied the history, cache, and cookies before. As far as I can see, there are no firewalls up. The website was created on the same computer and all the files for the site are on this computer.
I am very much out of ideas on what it would be. Can someone please help? Let me know if you need any more information.
Thanks
Lejla

Thank you all for trying to help. After I went on a few different computer and tried to access the FTP for the website and could not, I could see that there is something wrong with the server side of this site, nothing with my iMac(thank god). I got on with the support from the people who host our sites (again), I got an answer and now I'll try and figure out how to implement that.
Thanks again.

Hi,
I'm sorry you're having this issue with gmarks add-on. Maybe following answer from a top contributor will also work for you? (it helped another user whose gmarks didn't work after an update). See https://support.mozilla.org/en-US/questions/839481#answer-204324

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History") or via the about:permissions page.
Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks, cookies, passwords, cache, history, and exceptions, so be cautious and if you have a password or other data from that domain that you do not want to lose then make a note of those passwords and bookmarks.
You can't recover from this 'forget' unless you have a backup of the involved files.
It doesn't have any lasting effect, so if you revisit such a 'forgotten' website then data from that website will be saved once again.

Can't access certain website(s) now-

Has anyone else ever had trouble loading a website with Verizon wireless? I am having trouble loading two, these websites are linked. I have tried cleaning out my cache and bookmarks. The problem started when we had a prototype website done for us, and then the webmaster changed to a "new" website address for this. I cannot access the website with the new address, only the old one. I also cant directly access the linked to other website now. tMy wife can't access these website either, even though she has a PC and I have a Mac, so we thought it must be the ISP.

Hi community,
We want this device trouble to fixed for everyone so every site can be accessed. This 890L device is a 4G product that has had a glitch found while connected to 3G. We have found that while connected to 3G service, these sites are all accessible. Can anyone confirm if this has been tested and verified to be the case? If so, we have a fix to get the 4G connection to have the sites work too. If this issue happens while on 3G as well then we need to open an investigation ticket for that specific line.
The fix for those that have access to the sites on 3G is below. Please follow the directions below to install a software patch onto their computer. This patch changes the default MTU size from 1500 to 1428 which is acceptable on the network without the need for fragmentation. Please use the appropriate link based on the operating system.
Windows based `Set MTU Size` tool: http://production.4510.verizon.mifiupdates.com/Windows/MiFi4510LSetMTU_Win.zip

Linux based `Set MTU Size` tool: http://production.4510.verizon.mifiupdates.com/Linux/MiFi4510LSetMTU_Lin.zip
Once the zip file is downloaded, go through the below steps. Windows XP users will be prompted to do a reboot.
Unzip SetMTU_Win.zip
Double click on SetMTU.exe
Select value (default 1428)
Reboot is required on XP only

Can't access several websites after last security update

Hello,
After upgrading both my Macbook Air mid 2011 and iMac 2008 (with SSD) both running Mountain Lion 10.8.4 to the last security fix, I can't access from any of those two computers a variety of websites, for example:
www.opennicproject.org
www.gentoo-el.org
www.adslgr.com
These are only three. Almost half of Google's results are blocked. Using the terminal utility I am able to resolv some of them but not actually 'ping' them. I get no ping replies. I can access all these websites from other computers or devices (iPhone/iPad/Ubuntu desktop/WindowsXP laptop) on the same LAN. This problem exists only in the 2 macs which are up-to-date. I am sure that this problem is related to latest security update I did a couple of days ago, to both computers.
I'd like to know if anyone who have all patches installed up to the latest OSX version (mountain lion 10.8.4) has the same issues and can ping/resolv/access these websites.
Note that although I can't access these websites directly using any direct network connection, I can access them using TOR browser bundle for mac, which means that something is going on at a computer level.
I have checked so far:
- Applicationn Apple's firewall is not creating the problem (disabled/enabled all)
- ipfw/PF is not running with any ruleset
- LittleSnitch blocks just a couple of annoying outgoing connections. Nothing there (I disabled/enabeld it, same thing).
- Other computers access the websites/ping them/etc.
- I can access websites using TOR.
NOTE: It's not just 3 websites, it's something like 1 out of 3 DuckDuckGo links.
Ideas and thoughts are welcomed!
Best Regards,
PA

From the Safari menu bar, select
Safari ▹ Preferences ▹ Extensions
Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.
If you wish, you may be able to salvage the malfunctioning extension by uninstalling and reinstalling it. That will revert its settings to the defaults.

Not sure I understand you correctly.. Are you currently in China, and therefore unable to download the app? Also, which program is it that you're trying to get?

Can't access some websites - URL is hijacked by "unotelly" - ??

This has a virus-like feel to it... I can't access certain websites,. When I do, I'm bumped to a site for Untotelly.
I type: www.bbc.co.uk
And I go to: http://quickstart3.unotelly.com/?origin=http://www.bbc.co.uk/
At the top of that page I'm asked to "please update your IP address" (among other things) .. which I'm reluctant to do.
The question is: how do I stop this from happening?

I'd think that the DNS settings on your computer or router have been changed to unotelly's ones.

Can't access some websites. Possibly DNS problem.

This problem only started to occur a couple of days ago. I found that I can't access certain websites,but all the other computers in exactly the same network environment have no problem accessing them. I tried changing my DNS server settings from the servers my ISP provided to the Google DNSs, 8.8.8.8 and 4.4.4.4, and those websites I couldn't access before became accessible immediately, but some other websites, which I was able to access with the DNS provided by my ISP before, became inaccessible again. I tried using another set of DNS addresses, the same thing happened: some websites that I couldn't access before became accessible, but some others become inaccessible again. All these DNS servers that I used work perfectly on other computers in my network, so it has to be the problem of my computer. This has nothing to do with the browser, as all of the browers in my system have the same problem, even including the Internet Explorer in my VMware Windows virtual machine. I tried flushing the DNS cache with dscacheutil -flushcache, and it didn't work.

EA4500 - can only access youtube, google at a very slow speed, can not access anyother website

Got a new EA4500 for X'mas
After setting up the new router I could only access youtube and google at a very slow speed, however I can not access anyother website - facebook, yahoo and etc...
it would ping yahoo and google no problem
friend told me to do a tracert some ip address and his conclusion was the router is fully functional
ISP uses PPPoE, Im sure that the username and password are correct.
upgraded to the latest firmware manually, and holy hell accessing the router with no internet access is a pain in the **bleep**!
Please help and Merry X'mas

I've made sure that both the EA4500 setting were the same as the WRT54G, did not solve the problem.
IP Address behind WRT54G is 192.168.1.103

It might be a DNS problem. Release & renew ip on the status page of your router. Just make sure you are already using the latest Linksys smart wifi firmware, reset the router & reconfigure. You can download the firmware here http://homesupport.cisco.com/en-us/support/routers/EA4500.

Can't access my website through safari through linksys modem

I've just spent 6 hours with linksys support and all we could make work is Internet Explorer. But I mainly work on a Mac, which doesn't have IE and I'd much rather work with safari.
Here's the problem.
I have a bunch of websites all hosted under the same shared hosting account. At first I could access them while wirelessly connected to linksys router. Then the connection got very slow and eventually, I couldn't access my websites anymore. I could access all other website. In fact, I'm connected wirelessly and I can reach that forum, but I can't access my websites in that hosting account.
EVERYONE ELSE can access my websites though. And I can go anywhere else which has wireless connection and I can access my websites. So they're up.
I can also connect my computer directly to the modem and access my websites. It's only when I'm connected to the linksys wireless router that I can't.
So the idea was the problem is with linksys. I spent 6 hours with linksys support and all we could do is make it work on my PC with I.E. by selecting the following option: Internet options --> connections -->LAN settings --> and check "automatically detect settings.
How do I do that with Safari?? Any suggestions?

Hi Rick,
It's not a mac problem. I am able to access my router i.p address with safari.
The problem that I have is with the Mac AND my PC. They both cannot access my WEBSITES that are all located in one hosting account using Safari. For example, I can't access www.bullseye-promotions.com using safari or Firefox.
*What I need to figure out:*
it work on my PC with I.E. by selecting the following option: Internet options --> connections -->LAN settings --> and check "automatically detect settings.

*A better explanation of the problem:*
HERE IS THE CONFUSING PART... I can access my websites through a linksys wireless router outside my home. The problem occurs only in my home. I bought a new linksys router but the same problem remains.
Even when I hardwired through the linksys, I still can't access my websites that are hosted in that particular shared hosting account, except with I.E.
sometime I gain temporary access but then I loose it again. I think the linksys support guy told me it's about linksys giving the right public I.P address, or something like that.

Can't access any websites! :(

Hi all, I've been on BT Infinity for a month or so now and have been experiencing the same issue with one of my PCs. It connects to the HomeHub via Ethernet and runs Windows XP SP2. I can RD into it fine and FTP works too, as does HTTP! However, I can't access any websites at all. No other device connected through wireless has this issue. Initially I was using a static IP address because of port forwarding but the HH uses MAC addresses so I reverted back to DHCP. That aside, I've tried alternative DNS servers, flushdns and winsock resets and tools. These work for a few minutes then all of a sudden the websits stop appearing again! I'm very frustrated and would really appreciate some help as the BT Support team can't understand what I am saying!
Many thanks!

Thanks Keith, the disabling of the cache hasn't made any difference. I'm in Regedit as we speak and cannot find the parameters mentioned on the site, all I have is a 'ServiceDll' option in 'Parameters'...
Any idea where I can find the parameters they mention?
Many thanks.
You have to add the DWORD MaxNegativeCacheTtl yourself, and give it a value of about 5.
If you read the article its says that none of the DWORDs normally exist.
Also, did you read this on the forum?

Can't access one website... so annoying!

Hello, I'm new to this forum and I was just after some help with a problem I've been having for a month or so now.
I work for a website and for a month now I've not been able to access that one particular website. Every other website is fine. I've tried everything I can think of, flushing/renewing the dns and putting chrome and ie on the exceptions list on windows firewall are two that I can remember doing. I've also restarted in safe mode and the website still doesn't work.
I know several websites are featured on that websites server and I can't access them either. I also know for a fact that the website is running, when speaking to colleagues etc...
I thought it might be something to do with my antivirus (norton 360) but I tried to access that website on my fathers computer and he has AVG, so not sure if it's anything to do with that.
I would really appreciate it if someone could help me. The only thing I can think of now is it being a fault with the internet? I can't tell you how frustrating it is!!
Thank you in advance

Hi. Welcome to the forums.
There can be a few reasons for this problem, some form of local blocking via a security program (in the distant past, a rogue hosts file entry can cause this, and may still affect some people).
One of the easiest checks is to power cycle your router, i.e. disconnect the BB, remove all power including the plug from the wall, wait a few minutes and reconnect. This usually gets a new IP address (before and after can be checked by going to somewhere like http://www.whatismyip.com/). Try the site again.
Sometimes an IP address can somehow become stale, no idea why - but maybe there is some bad router code in the various networks out there and are not able to reconcile the website (even a DNS lookup failure for that stale IP address).
