[Smush Pro] Smush Pro not "smushing" images

I keep trying to run a bulk smush. After the smush is done, it says everything has been "smushed." Then when I re-run a test, it states that I still have 73 attachments that need re-compressing. I keep going through this endless cycle of doing a bulk smush, having the program state all 73 items have successfully been smushed but when it re-runs get the same message: Kara, you have 73 attachments that need re-compressing!

What else can I do?

Thank you in advance for your help.

    Pretty sure I’ve had this happen, there’s a couple reasons in my cases. One reason is that there’s a reference in your database to files that don’t exist, that’s usually indicated by file does not exist in a red banner warning. Second reason is the file permissions on your host. There’s a few tiers of file permissions, i.e. the Files and Folders permissions in your website hierarchy, the ownership of the files by the web server i.e. Apache if CentOS7 or www-data:www-data if Ubuntu. Then there’s directives setup inside of your configuration files under /etc/httpd/ if CentOS7 or /etc/apache2/ if Ubuntu, as well as the blocks in the servers loaded php.ini that could cause the inability to read/write objects on the server. Actually there’s a 3rd too I guess being Setenforce if on CentOS7 or otherwise your firewall might need to allow httpd rw content. In any case that’s all I’ve ever ran into causing my smush not to smush. Edit: here’s what I’d do, run a site health check and see if you’re also missing any PHP extensions smush needs. then check out the permission stuff. gl.
