No Image Uploaded with domain canonicalization in htaccess

[mltgroup]

Hello,

 

I installed OSC to a sub-directory. Added products/images and all works well.

 

Later I added an htaccess file to the root directory with the following.

 

Options +FollowSymLinks 
RewriteEngine On 
RewriteCond %{HTTP_Host} ^thedomain.com [NC] 
RewriteRule ^(.*)$ http://www.thedomain.com/$1 [L,R=301]

 

Now, when I add products in OSC, I try adding images, but after clicking preview I get: "Warning: No file uploaded."

 

The images directory is chmod777, so I'm not sure what to do.

 

Any advice?
