HT204088 I get a blank screen when I click on iTunes app on my ipad2

I get a blank screen when I click on iTunes app on my iPad how can I rectify?

SOLVED! I also received "Loading" message when I clicked on Apps store.
Go to Settings, General - ensure Restrictions are Enabled.
Also in settings, General Reset Network Settings.
You you then see Apple logo for a few moments.
Go to Settings, turn on wifi (you will need you network pass code)

App Store - blank screen (iphone 5S, ios 8)

I get blank screens for all tabs in the App Store except for the Updates Tab. I've seen some similar discussions around this in the forum, but nothing specific and recent to what I'm experiencing. My phone is a "work" phone and is configured with my company's specific settings, so I'm not sure if this a possible cause or not (with respect to security, firewalls, etc.). I can't imagine it would be since I'm using my Apple account, but stranger things have happened. Also, I just recently (last week) received this phone and the App Store was working just fine up until a couple days ago. As far as I can tell, nothing changed between then and now.
Iphone 5S
IOS 8.1.3
Anyways, looking to see if there's anyone out there who has seen this and knows of a solution. Thanks,

My iPhone 5c with iOS 8.1.3 is also demonstrating this problem, as at Feb 7, 2015
However, prior to this, noticed that Updates to installed Apps needed 2 or 3 attempts, so I knew something was up...
So, surfed the web and found some "solutions", but they did not fix the problem;
1. Turn off iAds - no good
2. Advance date 1 year, hard-reset & try again - no good
Went to an Apple store, they checked a few things, all OK so we tried a Reset > Network Settings - no good
My phone also is "provisioned" by my company, where they suggested the profile could be the problem (but I couldn't see how).
So, made a Genius Bar appointment for Feb 26, I'll update here with the outcome...
One thing, though, the problem seemed to occur after I connected my phone to my work PC and removed some Apps from my library. iTunes on the MS-Windows PC hung/behaved strangely as well... Not sure if it is related.

IPad mail app displays blank screen, then crashes

When I go to my aPad mail app, there is just a blank screen, After a few seconds, the app crashes. I can't delete the app because it appears to be "built in". my mail works fine on MacBook Pro and Nook.

Hi A436,
Thank you for contributing to the Apple Support Communities.
If you only see a blank screen in Mail, and then the app quits, try removing and re-adding your mail accounts from Settings > Mail, Contacts, Calendars.
You can use these steps from Get help with Mail on iPhone, iPad, and iPod touch:
Tap Settings > Mail, Contacts, Calendars.
Tap the affected email account.
Tap Delete Account.
Add your account again.
If the Mail app still quits unexpectedly after this step, you may need to back up your iPad and restore the iOS software:
Use iTunes to restore your iOS device to factory settings - Apple Support
Sincerely,
Jeremy

Update notification shows there are updates but when I click on the update option it shows a blank screen

The update option on the app store shows a notification that I have 'n' numbers of updates but when I click on the update option it only shows a blank screen. Even after updating the apps individually from the purchased option, the update option still shows a blank screen instead of "All you applications are up to date". Please help.

Many people are having this problem for the last couple of days. According to Fly150in another discussion, this will work.
If you want to update the Apps while waiting for Apple to fix Updates:
1. Go to App Store
2. Select Purchased
3. Select All
4. Scroll down to find the Apps showing update
5. Select update on the Apps
This should update the Apps and get rid of the update count in App Store.

SAP Mobile App System Monitoring = blank screen

Hi guys,
I encounter problems regarding System monitoring App on Android. I followed the instructions in SCN wiki to setup the gateway and ODATA to enable the monitoring via the mobile app on android.
My app connects to the gateway without any errors but did not show anything. The screen is just blank (see attached file). I have setup one technical monitoring in my solution manager 7.1 SP7 (to monitor the solution manager itself). Do you have any clue whats going wrong?
Best regards
Marco

Unfortunately I can't try solman_admin, because I'm getting the following while try to access the data:
"No authorization to access Service '/AIGW/TECHMON_0001'"
I try to connect with my user and receive some XML data. But something is strange. As far as I know, the URL prefix should be "sap/opu/odata/AIGW" but this doen't work in my case. If I try "sap/opu/odata/AIGW/TECHMON" something happens, but I see no data (blank screen). Service Name is set to "TECHMON". While I connect to this url via web browser, I get the following XML data:

Seems a bit to short in my opinion. The technical workcenter seems to be OK, there are no blank pages. Any suggestions?

Numbers & Pages Apps for iPad. Blank Screen looking at iCloud.

Apps work correctly when iCloud Documents & Data turned off and apps preferences delselect Use iCloud.
Once use iCloud is selected under iCloud preferences and App preferences startup sceen goes to a blank screen. ie. No + symbol on upper left etc.
Using iOS 7 with latest updates and newest Numbers/Pages on a iPad Retina display.

I suspect a lot of hospitals are doing this.
Could you give a more detail description of how things work on a PC Laptop?
Is the data on a network share?
How does the data get to the PC?

Is there an all in one program running on the pc to access the data?

App Store problem - blank screens

I'm getting blank screens in App Store on my iPad 3 with ios 6 - charts and categories screens are blank. Blank screens also when redirected to a particular app from a web page link. Wife has same iPad and hers works perfectly. Have rebooted, turned off and confirmed good wifi signal etc. everything else seems to be working. Any ideas please?

Saw this on another post.
Applecare Senior Advisor Txx Bxxx (I have his contact info in an email he just sent) just confirmed with me that the problem people are having with the App Store not loading is an apple issue with there servers, ITS NOT YOUR IPAD so don't go restoring it! It's not happening to everyone however but they are looking into it, its really hit or miss.

Try this first - Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
This works for some users. Not sure why.
Go to Settings>General>Date and Time> Set Automatically>Off. Set the date ahead by about a year.Then see if you can connect to the store.

My video app that is preloaded on the IPAD will not open. all I can see is a blank screen. Does anyone have any suggestions on how I can fix it?

The "The connection was reset" error message can be caused by a bug fix for the BEAST (Browser Exploit Against SSL/TLS) attack that the server doesn't handle.

Internet Explorer web browser app for iphone 4?

Is there an IE web browser app or one that mimics EI?

You're not going to get something more like a desktop browser (if that's what you mean by regular) on any device with a 3.5 inch screen.
Safari seems limited.
In what way? Safari is almost universally regarded as being the best mobile browser on any device. It's support for web standards, and its rendering engine are far better than what you are used to in IE.
Exactly what do you feel is missing?
Are you referring to Safari's HTML rendering engine (it's ability to display websites accurately), or features of the browser itself?
Well I guess I was expecting too much for a phone browser. But thanks for the info on Safari.

Blank screens for add ons, apps, downloads, About Firefox

Trying to add an add on, I find I get only a blank screen under Tools/Add Ons (status bar at top seems to get to end of tab and hang). Same thing under Downloads, Apps and Settings/Mozilla/About Firefox.
Running Android 4.4. Not sure of Firefox version, but it seems to be current.

In the first place, in [http://www.cnn.com/video/?/video/world/2014/07/07/cnni-vo-turkish-f-16-jet-low-approach.cnn&hpt=hp_t5&from_homepage=yes&video_referrer=http%3A%2F%2Fwww.cnn.com%2F this link] an ad starts playing automatically on my Android (followed by click to play) where in Windows I just get the FlashBlock symbol to click if desired - so FlashBlock still might be an advantage. I admit that the auto-playing video on my Android that made me post the problem auto-played in Windows as well - FlashBlock not withstanding.
Aside from the issue of FlashBlock though, if I don't get a ''Browse All Firefox Add Ons'' button under Add Ons - but only a blank screen, don't I still have a problem? Three other people show as having this problem - I assume that's the same blank screen issue. Can anyone suggest a fix?

My mail app quits a few seconds after launching. I get a blank screen and then it goes back to the starter screen

THe mail app on my ipad 2 quits right after launching. This happened as I was forwarding an email with a long attachment. Now I get a blank screen with just the icons, no mail mailboxes etc. after a few seconds that blank screen disappears and we go back to the starter screen. I tried rebooting, relaunching but no luck so far. Can somebody help me? Thanks
Hans V

Have you tried removing the email account from the app through settings? I would try removing it, rebooting, opening the email app to see if it still crashes, & then adding it back your email account.
If you're leary about causing more issues while you're not home, you could always try using a third party mail app (there are many), accessing your email through it...not a fix for your problem but a way to deal with the situation until you can get it worked out.
Resetting all settings on the iPad (not deleting content) is a good way to clear many errors as it can remove leftover cache files & files that have become corrupt.
Sorry I couldn't be of more help. Good luck & let us know if you get it working.
