Hi, blog is chennairains.com and i've run a script in phpmyadmin to point all images to cdn.chennairains.com (the uploads directory also has been moved) 

its all sucessfully done and necessary changes made to wpconfig and htaccess to ensure media files go to cdn.chennairains.com 

when users comment and upload media on wpdiscuz, the uploads folder again gets created in chennairains.com instead of cdn.chennairains.com. is there any way this can be corrected?
