When I encounter Done but with error messages, I view sourse, copy and paste into Dreamweaver and find the culprit causing the error.
I did this with your page, and the error is on line 280, except your page only has 279 lines of code (when rendered), so I can't say for sure what the error is. Check your theme and make sure it's not using a javascript, and if it is, make sure it is properly used. It could be your footer.php, or an include thats formatted (coded)wrong, I don't know for sure.
Try a different theme, f the error goes away, it's a problem with your current theme.
