If you go to the page.

Then if you click on any of the navigation on the left the firefox error console pops up. I had figured out most of the previous errors that arrose from this site, but I can not figure out what the last error is saying?

People are getting annoyed, and some browers show the error and some don’t. The site itself works fine. Except for the annoying errors.

Anyone know what the heck I need to fix??

Thanks.
