General Support: Comments problem

When I try to post a comment, it takes me to a general browser "Problem loading page" error. When I hit the back button, a message box appears saying "Comment did not post! Please fill in required fields." However, if I log in to the plogger admin page, the comment is waiting there to be approved.

I would really appreciate some help if someone can tell me how to fix this. I've tried searching this forum for the answer, but I can't figure out what to do. Thanks!
