Blank Login?

Hi
I have a problem with my admin username and password prompt window, It's blank. I can't install new software or complete any operation that requires my admin username and password.
I did some research and found a discussion that said it was a Java bug and to install manually a new update. I tried this through Terminal, no fix. I tried reverting to Java 6, no joy. Any help would be appreciated.
Thanks.

Uninstall SIMBL as follows. Back up all data before making any changes.
Triple-click anywhere in the line below on this page to select it, then copy the text to the Clipboard (command-C):
/Library
In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V), and press return. A folder will open. From that folder, delete the items listed below (some may be absent.) You may be prompted for your administrator login password.
Application Support/SIMBL
InputManagers/SIMBL
LaunchAgents/net.culater.SIMBL.Agent.plist
ScriptingAdditions/SIMBL.osax
Log out and log back in.
Make sure you never reinstall SIMBL. It’s likely to come bundled with another third-party system modfication that depends on it. If you want trouble-free computing, avoid software that makes miraculous changes to other software, especially built-in applications. The only real exception to that rule is Safari extensions, which are mostly safe, and are easy to get rid of when they don’t work. SIMBL and its dependents are not Safari extensions.

Having a blank login at start up

previously when i started my computer up i had a blank login where i filled out the username and password, but at some point it changed to where my avatar and name is provided along with the guest account. i would like to revert back to the old setting but am not sure how?
my login options are set as is
figure#1
When i just log off it shows what my start up page used to be which was all grey with an insert area for the user name and password, similiar to figure#2 except i had to fill out my name and password and contained no avatar.
figure#2
That is what my startup login looks like now too except even though my guest profile is disabled it shows up during startup as an option. i havent tried signing into it but that shouldnt show up if it was disabled right?
please help. thank you.

Blank Login screen - DNS issue

At my company's site we seem to be experiencing an intermittant blank login screen but only for the microsoft sign in page, the Skype sign in page loads up fine.
When skype loads up we get this screen:
And the users choose "Microsoft account". They should then see this screen:
Instead they get this:
At the bottom there is a warning message saying the following:
"This page contains errors. Go back"
The site is using OpenDNS to filter DNS queries for the PCS and the policy is fairly locked down.
On any affected PC, if I:
- Close Skype
- Point the DNS settings to something like 8.8.8.8 (google's DNS server)
- Load up skype
The login screen (image 2) loads up normally. The user can login and I can then flip back the DNS settings to the OpenDNS server and there are no further issues.
What this means is that Skype is trying to contact a Microsoft/Skype server somewhere on the interent and because it is not on my OpenDNS whitelist it gets blocked and fails like in image 3.
My question is can anyone tell me what the server is? I went through the OpenDNS logs and whitelisted a bunch of microsoft stuff and some other things related to certificates but still no luck.
Solved!
Go to Solution.

Evetually I took Techfreak's suggestion and sniffed the packets with wireshark. Was annoyed to discover that the root cause of the issue was suspiciously named sb.symcd.com.
Some quick Google-fu led me to a page which advised that this domain should be whitelisted for Lync installations. Hmm.
Why microsoft could not use more intuitive/descriptive server names is a mystery. Anyway, I whitelisted *.symcd.com and from the limited testing it appears to be resolved.

Blank login screen on the iPad keeps popping up and wifi disconnecting after 20 seconds

hi, we have an ipad running IOS 5 that keeps having a blank login screen on the iPad keeps popping up and wifi disconnecting after 20 seconds.
I am yet to find out why this is, any clues? (note that both apple.com and facebook are blocked at the router, but nothing else)...

actually we cannot due to policy reasons... it appears through testing that the iPad is phoning home and sending private data to Apple regardless, it is also odd they placed these PRIVACY settings in About hidden away so that no-one knows they are there.
From the iPad homescreen, tap on Settings > General > About
Tap on "Diagnostics & Usage" > select "Don't Send"
So... anyone else know why if we block Apple, the iPad disconnects from the internet via Wifi?

Upgrade to 4.1 results in blank login screens

So I started with a fresh Windows 2008R2 server and installed 11g (11.2.0.2). Then I got the embedded PL/SQL gateway up and APEX functioning (pre-installed 3.2 version). I ported over an existing 3.2 application schema from a production box and that worked fine. Now I'm trying to upgrade to APEX 4.1 and I'm running into problems.
ran apexins.sql just fine - no problems. Check came up clean (no errors) and upgrade was complete, but when I went to run an application, I get blank pages. My application comes up with the home page, but login doesn't work. The Admin login shows a blank page (view source does indicate a page being generated), as does the Developer login.
I ran epgconfig and it showed the ANONYMOUS user as locked/expired, so I unlocked the account and changed the password, but this didn't do anything. I have tried to run apxldimg to load the images, but it fails each time with the same error:
SQL> @apxldimg.sql /Install/Oracle/apex_4_1_EN
PL/SQL procedure successfully completed.

SQL>I unzipped the files into the G:\Install\Oracle directory and renamed the directory to apex_4_1_EN as it is the English-only download and I had the full version unzipped in the same location. I have tried different versions of the path and even ran the script from the ORACLE_HOME\apex directory in addition to the unzip location - no dice.
Please help.
PS to Oracle: Why are these upgrades/installations so temperamental? I've been working oracle from 9i up and every single upgrade is a major headache! (probably because the documentation is so cumbersome)

So it would really help in the Oracle documentation if they would provide a completely separate UPGRADE guide as opposed to an INSTALLATION guide, as the instructions are significantly different!
Here's what to do:
1. Shut down any APEX-related processes or services including the HTTP server (if you are using it).
2. Unzip the 4.1 download file to any location of your choosing.
3. Rename the ORACLE_HOME\apex directory to indicate the version you are currently on (apex -> apex_3_2, etc.)
4. Copy the entire unzipped folder called apex from the new download to ORACLE_HOME. You should now have TWO apex directories - one versioned for backup purposes.
5. Now you do the upgrade. Set your prompt to start from within your ORACLE_HOME/apex directory
a. First run @apexins.sql to install the new schema and all the necessary objects.
b. Next use the @epgstat tool to show you the status of your installation and users. Make sure the ANONYMOUS user is unlocked and OPEN. Also make sure that you have given permissions to the APEX_PUBLIC_USER and configured access to XMLDB. Change the password to the ADMIN account if necessary.
c. Now you should be able to run the apxldimg.sql script and have it complete without error. I used the full path of the ORACLE_HOME.
6. Restart any processes.
7. Bring up the administration login page at http://localhost:port/apex/apex_admin. (You need to substitute for whatever port value you are using and optionally substitute for localhost.)

APEX listener returns blank login page

APEX 4.2.2
APEX listener 2.0.2
Glassfish 3.1.2.2
Platform is 32bit Linux, Amazon EC2
I am reasonably certain that I have deployed apex.war and i.war correctly to Glassfish, and defined a virtual path and a database connection correctly.
When running Firefox on the EC2 machine, browsing to
http://localhost:8080/apex/dad1/
returns a login page no problem. But browsing to the external, publicly visible, address (I have to obscure the actual address, I'll use a.b.c.d) either from the hosting machine or across the net returns an empty page:
http://a.b.c.d:8080/apex/dad1/
This succeeds:
http://a.b.c.d:8080
I get the standard Glassfish page so I know Glassfish is listening on that address.
I have also tried starting the listener standalone, and I get the same effect: it returns a login screen when browsing to the localhost, but going to the external address I get a blank page.
The pages really are blank, nothing shows in the page source and this is all Firebug returns:
<html>
<head>
<link title="Wrap Long Lines" href="resource://gre-resources/plaintext.css" type="text/css" rel="alternate stylesheet">
</head>
<body>
<pre></pre>
</body>
</html>
I have been trying to enable tracing of the request on the server side, but I haven't yet found a way to produce the equivalent of an access.log. Searching the forum did produce a couple of references to "routing rules" but I have been unable to find what and where these might be.
As the listener works perfectly when going to localhost, I cannot believe that rthis is the common problem of not finding imges, or an issue with url mapping. But I am of course open to any suggestions!
Any insight will be welcome.
Thank you for your time.

Fixed. Finally tracked it down, a redirection problem fixed with patch 16760897.
Thank you to anyone who looked at this, sorry to have wasted your time, hope posting the solution will assist someone else.

Ebusiness suite R12 Blank login page

Hello
I have just installed ebs r12 on Windows XP via VMware but cannot get the e-business login page to come up. When I type "http://<host name>.<domain name>:<HTTP port>/OA_HTML/AppsLogin" I get a page cannot be displayed. But if I add .jsp at the end then I simply get nothing, not even the page cannot be displayed message comes up. I can connect to the DB using SQl Developer.
The installation completed without any errors. I am very new to this but would really appreciate if someone can give me some direction on what to do. I come from an applicaiton support background and find this whole product quite a minefield to navigate around but if someone can also point out some learning materials then that would great too.
Thanks
K Hussain

Blank Login Page after Upgrade from 4.0.2 to 4.1

Greetings,
I just upgraded one of my Apex environments from 4.0.2 to 4.1. After the upgrade, I tried to access the login url and I get a blank page. Nothing on it, just a white page. However, if I do a View Source, all the html code is there. I wonder if it somehow lost where the Image, CSS and Javascript files are located. I am using the Apex Listener running under Weblogic 10.3.3. The Apex Listener was just a standard install with the image location being '/i/'. I am not sure how to debug this. Any help would be appreciated. Here is a snippit of code from the View Source.

I had the same behavior using apache mod/plsql the solution is:
a) shutdown apache (opmnctl stop)
b) unzip the APEX install file in a directory on the machine where apache is installed
c) correct in the dads.conf the virtual dir /i/ to the "images" directory of the unzipped file
d) restart apache (opmnctl start)

BT Sport Online Player - Blank Login Page

Logged in, click BT Sports 1, 2 and ESPN but the page goes blank and the tab at the top flickers from "login page" to "connecting" and back again. But the main page remains completely white blank.
I'm on a Mac if that makes any difference.
Why no work?

On a Mac, are you using Safari (with Silverlight plug-in) or Chrome browser? Chrome is not supported.

Empty/blank login screen

Today I opened Skype as I do every morning, so until yesterday everything was working. This morning, there's just an empty, white screen. The contact colums is grey, even if I still have all contacts saved. I can jst open my profile page. I tryed to uninstall and reinstall Skype, but it didn't work. Skype is updated at the last version. I have a MacBook Pro, with Maverick 10.9

It's possible that scripting in your Internet Explorer is disabled by an Antivirus/security software.
What Antivirus/security applications are installed on your computer?
Meanwhile you can try the “legacylogin” workaround, which should enable login to Skype using the old legacy login window. However, you will not be able to login using Microsoft account (email address).
Quit Skype. Make sure that you don’t see any Skype.exe processes in Windows Task Manager. If necessary, then stop these processes.
Open this folder on your computer:
C:\Program Files (x86)\Skype\Phone\
You should see there the Skype application file (Skype.exe). Right click on the Skype.exe file and select: Send to – Desktop (create shortcut). Right click on the newly created shortcut and select Properties and then the Shortcut tab. In the Target field you will see now:
"C:\Program Files (x86)\Skype\Phone\Skype.exe"
Click with your mouse on the text in the Target field and move your curser one space after the last quotation sign and add the text /legacylogin. The text in the Target field should now read:
"C:\Program Files (x86)\Skype\Phone\Skype.exe" /legacylogin
Click OK to save the changes. Start Skype using this new shortcut. Can you now login to Skype?

Not able to log onto Skype. Blank Login and Possib...

I've been reading around trying my best to find a fix to my problem. I apologize, I am not that computer savvy
I am on windows 8.1 and 64 Bit
It started off with skype not allowing me to open up the home tab to see everyone's status updates. Sending me to an IE page asking me to download something. This was the first time such has happened to me so I assumed it was a virus So I did a scan on my computer and restarted it. When skype was suppose to open. It did not. Instead it took me to a Blue page where the login would go and nothing was there. I then reinstalled skype.
From this point where I am now. Skype installs and then comes to a white screen. Then moving to a download over the white screen wanting me to download Index.html I have tried opening and saving...What happens is it takes me to IE and then the download area for IE... Everytime I try to open it creates another file asking me to save it again. That's how far I get.

Please, run Sysytem File Checker Tool (sfc /scannow).
