[support] Imagecache stopped working

I recently started hosting on rackspace.com. I used their testing url to set up the site, imagecache worked fine. When I transferred the domain over imagecache stopped working. - Folder permissions are wide open - No errors in drupal or php logs - temp folder set up and permissions wide open - cache cleared - Imagecache flushed I am not sure what else to check. Is the old testing domain stored somewhere on the site? Eric
