I am trying to bulk optimise my entire library of 12,000+ images. I tried the latest version, and it did 927 before it seemed to time out (I didn't get any errors and the timer kept going, but no more images got processed.
After that I tried doing 500 at a time from the Media Manager, however when I go to the third page, select all my images and choose 'Bulk optimise' I get the following error:
ERROR The requested URL could not be retrieved
Is there a maximum number of images that I can do at a time from the media manager?
