iPhone 5s Settings Facebook Login Won’t Work, Help?

Since today, I’ve suddenly been having issues logging into facebook in the settings, I try logging in and it’ll logout and tell me to login, perfically saying “Enter the Facebook password for “—————“ in Settings.” on a box with “Settings“ and “Cancel” options.

I tried restarting my phone, uninstalling and reinstalling Facebook and reseting my password, nothing has worked.
