W3 Total Cache – error mime detection

I have a client site (hartmanjewelers.com). I installed W3TC so that I could apply MaxCDN. I have the CDN pull zone created, but it's not working completed.

Hosting – GoDaddy Shared

What I've noticed is that when I run a compatibility check it says that Mime detection is no enabled.

I noticed that for other clients that are running GoDaddy shared hosting, their compatibility shows "Installed (file info)".

I called GoDaddy and they said that it was a .htaccess file issue that we would handle on our end. I copied the 'mime' section from the working client file and added to the mime section of the Hartman file, but it didn't work.

Attached:

Any/all help is greatly appreciated.

Thanks,

Jeff
