Problems using Facebook

Hello,

Hopefully someone out there will be able to help or is going through the same thing as I am on Facebook and will have some suggestions/answers for me.

Lately I am able to sign in, but as soon as signed in I cannot change my status line, I cannot comment on anything friends have posted or said, cannot comment on any photos....it tells me "ERROR ON PAGE" at the bottom of the screen.

Not only that, everytime I sign in and want to change my page I get a pop-up that says:

"Are you sure you want to navigate away from this page?
false
Press OK to continue, or Cancel to stay on current page"

This is driving me absolutely crazy - I'm going on day 5 of this crap and I have even tried to search for a Contact Us type thing on FB and cannot even find that to blast someone and tell them to fix it.

HELP!! Thanks everyone
