I continue to receive the "error on page" message while on Facebook. This does not allow me to post or download friends. Please let me know how to get this off the site so I can use Facebook as usual. Thank you,

Hi,
I realize this is little consolation, but Facebook is like a continually changing "Beta" program. Changes are made to try to extend it continually and some have unintended results. The thing to do would be to contact them with descriptions of your error, result and system. I have at times seen errors come and go there and elswhere.
Peace,

I'm with crigby, I get Facebook errors quite often... they usually resolve themselves once I reload the page.
Also have trouble with my wall updating sometimes but again that fixes itself.

You could also try using something like CCleaner, it helped with my problems (on other sites)
