I initiated a smush request on Friday and it has still not completed. I was able to retrieve 1367 of 2328 images, but I no longer have an option to fetch the remaining smushed files. The only option now is to "Send Smush Request", to which I receive an "Image file not found" error message.
When I view some of the images in my media library I see that they are "currently smushing."
I've tried uninstalling the plugin and reinstalling, but the results are the same. See this link for three screen captures of what I am seeing.
Please advise or reset so I can try again. Thanks.
