Feedback Comment system bug?

Hi,
I have a problem leaving feedback/comment on an ad listing. I click on comment and type the comments and click “Submit Comment” button, then it goes to an error 404 page saying
“This is somewhat embarrassing, isn’t it?
It seems we can’t find what you’re looking for. Perhaps searching can help.”

Then if I go into “My Account” section and click on “Feedback” or “View Profile” it says that there is zero Feedback, both User and My Feedback, and the toolbox shows zero comments as well. Not sure whats happening here. Another poster in the forums has the same problem in the Auction Theme forum. Thx
