I found a limitation the bulk smush feature.
Ran the smushIt
found several images that had an incorrect path in the meta_value field in
It seems that the paths reflected a previous host. Weirdly, the images show fine.
Anyway - I corrected the paths via a SQL update statement.
Smushit still thinks the file paths are invalid because it stored that information in wp_postmeta.
Feature suggestions >>> Smushit needs a way to re-try files it previously had trouble with while ignoring ones it had success with. Also, clean up database entries when Smush.it is deleted
