I installed the WP Smush Pro plugin and tried to run it. It has been running all day long (4 hrs) and it still says 116 of 116 attachments have been sent for smushing but it still says "0 of 116 attachments fetched".

I tried temporarily inactivating all of my other plugins and then running smush it but no go.
