IPhone Facebook app won't open after update?

I just updated my Facebook app like two days ago and it just shows a white screen flash and goes back to the home screen when I try to open it. I even uninstalled the app and re-downloaded it. I also restarted my phone, and still the same thin happens. Any way to fix it?! Everything else on my phone works just fine!

Make sure your phone is on the latest software

uninstall app

re install app

close it (press home twice and remove it from list)

try again

mine did it and it worked after i did that

failing that do a hard reset (power and home together for about 20 seconds)

also make sure its not jailbroken that could be the reson why or download a free anti virus for your phone too.

That worked great after 2 days of trying everything

My phone is doing the same thing. Tried all suggestions above and it still will not open

  • Why won't pictures open after getting hard drive transferred? I took my laptop in a while back to have everything transferred to a new one. Now, some pictures from a family vacation won't open! It says "File format not supported," but all my other pictures will open and they were all taken on the same camera (iPhone). It's about the only vacation my family has ever taken so I'm really sad about it. Why would this be happening? (PS the computer guy was extremely sketchy!)
