ok, I guess I should have looked closer, so after reading the last few post I realized that I change

Rewritebase /zencart/
to Rewritebase /

in the .htaccess file, and great no more error!

But now when you click on a category the only thing that happens is that the page refreshes, but I don't get anything other than the home page. The web address changes, but nothing else....Ideas?
