I am getting "error on page" when I try to use any of the active links on Facebook only...please help!

I am having alot of issues with links working on facebook. Everytime I try to confirm a friend, click on the links to use the trouble shooter, access any features on the site, write on walls, or reply to mail I get an error in the bottom left hand corner with a yellow exclamation point that says "error on page". The page I am trying on does not change it just stays and nothing will work. I can get to the apps, or get to anywhere on the site the error only happens when I am trying to use any of the features that I am on. I am not blocked and I do not have my facebook disabled and my grandmother is having the same issue on this computer.

I am using IE 7 with Windows XP
Java Sun~enabled and working fine as I tested it on other sites.
Only happening on Facebook no other sites.
Error only started occurring within past 24 hours was working correctly before.
Did virus scan and found nothing.
Have not changed any setting on pc since before the error occurred.

Please help!
