 * Hello group,
    I have a mutlisite setup for WordPress using a premium theme that
   uses TimThumb. When doing an export from one site to the other all the thumbnails
   break but showup in the media library of the newly created site. I tend to think
   this might come back to a wordpress better security settings. I am using the 
   subdomain format, I have added all the sites / subdomains to the array for TimThumb
   and turned off the “filter suspicious URL queries” in WordPress Better Security
   but the error persists. Perhaps a directory permission error? Any light you can
   shed would be fantastic.
