Help Facebook Authentication Error

[socialnoy]

I recently logged out of Facebook and when I tried to log back in I got an authentication error. Took my phone to Sprint where they un rooted my phone and after 2hrs still couldn't find and answer. Has anyone had this issue and if so what can I do to fix it.?

if facebook was the only thing wrong. I do not believe I would have taken my phone to sprint. However when you were rooted you could have cleaned cache / dalvic and maybe logged on to facebook through the Browser and see if that would let you then try the program again. Make sure your login name and password are correct.

Yeah i went to sprint with the hopes that it was a bug going around but turned out to be just something up with my phone... They restored everything back to its original settings and then it still didn't work. I cleared everything that i could find to clear and made sure my account password and login info was all the same and its still giving me the error message. I can log on with my phone but just not the app. Actually using my phone internet is a little funny too. Every time i post or look at a post it jumps back to the login screen.. Very frustrating and i'm running out of ideas on how to fix it. Just went to facebook on the pc and i'm looking at all the security options and there is nothing listed as my recognized devices. I'm wondering if this could be the issue???
