After installing this rom. (I flashed it over 5.1 without wiping) I tried to log into my Facebook account. It let me the first time but than it didn't show my contacts, Which i did press to sync all. So I tryed exiting the app, going into Chevytools and fixing permissions, than I rebooted. After that I attempted to log into the fb app and it wouldn't even let me log in. It says error occurred. Does anyone know how to resolve this. As I use this app on a very regular basis.
