well i changed the server & added the files.
Here are list of artists: http://www.shrishtiart.com/artists.php
when clicking any artist, detailed page is : artist-details.php
.htaccess file has:
RewriteRule ^artists/(.*)$ artist-details.php?artistlink=$1 [NC,L,QSA,T=application/x-httpd-php]
Works fine on my local server but not on main server.. getting 404 error on main server
