IPhone 5 won't stay signed in to websites like Facebook?

Ok so when I log into Facebook via Safari on my iPhone I constantly have to log in and it's the same with other sites like that. And it's only happened since the iOS 7 update before it stay signed in. How do I fix this I don't know how.

Mine did something like that the other day but it didn't sign out, everytime I went onto an app it stayed on for a few seconds then just went off. There's a new update it's called iOS 7.0.2 update it and it should work because it's for things like that, improved bugs ect.

Though I deleted it? :/
  • One Direction Signed iPhone 4 Case? I recently saw a picture on twitter of an iphone case that had one direction's band members signatures on it, I know it was not legitimately their signatures they were obviously manufactured like printed on because I'd seen the same exact ones with their real names signed underneath their signatures on some of their other merchandise and such haha. So I was wondering if anyone knows where to get something like this?
