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.

Any/all help is greatly appreciated.
