I'm not completely sure I understand what you are describing, however there are some fairly standard things you can try, if you have not already done so.
For problems with Safari, the first thing to try is to
Clear Cookies and Data. You can do this in the Settings app under Safari.
You should also make sure you have not accidentally entered Private Browsing mode. This mode is indicated by a dark gray title and URL bar. To enter/exit Private Browsing mode, tap the URL field so that the keyboard comes up. Above the keyboard, on the left, you'll see the Private button. Tap to switch modes.
Below are the more general fixes that come in handy for a variety of issues.

The Usual Fixes
------------------------------
When you have problems with an app it's a good idea to clear it from RAM.
Close/Clear the app:
iOS 6: With the problem app closed, double tap on the Home button to get the multitask bar. Tap and hold on any icon in the bar until they jiggle, then tap the minus sign on the problem app.
iOS 7: Double tap the Home button to get the multitasking display. Swipe up on the problem app's thumbnail image (not the icon).
If that does not work try a restart,
Restart: Hold down the power button until the power off slider appears. Slide it off. When the iPad finishes shutting down, hold down the power button again until the Apple logo appears. Apple recommends you restart the iPad at least once a month.
and then a reset if that does not work.
Reset: Hold down the power and home buttons until the Apple logo appears. The iPad will reboot. This usually takes a bit longer than a restart.
Reset All Settings: Another, somewhat more drastic thing you can do is Reset All Settings. You'll find this under Settings > General > Reset > Reset All Settings. It won't erase any of your content, apps, or accounts; but you will have to go through most of your other settings and re-tweak them back to your liking.
Do not confuse this with Erase All Content and Settings.
