Based on this topic: https://www.ads-software.com/support/topic/do-not-regenerate-the-name-if-the-image-already-exists/#new-topic-0
Every time the plugin renamed the image I updated the post with the new name because the File Renaming on Upload plugin changed it because the option was {datetime} and the name changed at the end because it updated the second one. Ok, but I have had to update the image more than once. The plugin executes the compression of the image several times? Because if it executes it only once, ok, I would update the image of the post, but then again the name was updated and again the name was updated. I think that CompressWP compresses an image several times, is this correct? If so, then it is a bug.
there is a conflict between File Renaming on Upload and CompressWP
]]>Running into this error on a dev site to test.
Cannot save compressed image. Please try again!
Also, image sizes are not showing in the CompressWP menu in wp-admin.
