Follow up on my situation…
I always use backups through Cloudways. However, when I use previous backups (that have always previously worked), the Media File Renamer (Free) plugin will automatically update itself to the latest version (5.2.9) so I am not able to go back to the previous version (5.2.8) to test.
I’m not sure what has happened. I have been developing other things on my website (using Cludways backups) without any issues. Then all of a sudden I started getting the white screen “There has been a critical error on this website. Please check your site admin email inbox for instructions.” error message and unable to move forward until I go in and disable all plugins through FTP. Once I go back into WP Admin, I was able to pinpoint the issue with the Media File Renamer (Free) plugin. I can activate all my other plugins with no problem but as soon as I update Media File Renamer (Free) – I get the same white screen error message.
I’m not sure what else to do at the moment. Maybe it’s on my end or maybe it’s the plugin, I’m just not sure. However, I think a new version of Media File Renamer (Free) was uploaded during this time so it makes me wonder.
Any help you can provide will be greatly appreciated.
I think the issue might be the same as other of my users experienced during these last 48 hours. I wrote a blog post here: https://meowapps.com/php-fatal-error-licenser-missing/. Does that fix it?
