Hello All, I just finished installing this contrib ( i have many others installed also, but none that should conflict ) and when I go to my site all I get is: Internal Server Error 500. The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script. I have read that a lot of people have this problem but have not yet found the solution. Something to do with the .htaccess file I assume. its running on my own windows server with XAMPP. Thats with apache, not IIS. Is there something special I need to do? The store root is located at e:\xampp\xampp\htdocs\catalog\ on the server. HELP PLEASE!
