 * Hello,
 * I have a problem with the function bulk optimize, the progression bar does not
   appear I have only the spinner which turns during hours and no images is optimized!
 * On the other hand when I go in Media the function optimize works individually!
 * I am on a ovh server.
 * Thank you for your assistance.

 * Sounds like a javascript conflict. Check the javascript console in your browser
   and see if there are any errors.
