Topic: Changes in ImageMagick6-libs?
Yesterday, I updated one of my servers (RHEL 7, PHP 7.2.12 from Remi) from ImageMagick6-libs-6.9.10-14.1, to 6.9.10-15.1. Immediately after performing this update, some of my WordPress sites began displaying errors when uploading images -- specifically, WordPress was no longer able to generate automatically image thumbnails. The page displayed a vague "HTTP Error" message that didn't really tell me anything, and the error wasn't logged in the php-fpm log file.
Reverting that RPM update immediately resolved the error.
Where should I begin in trying to identify the differences between those two versions of the package? I'm more than a little out of my depth, but everyone has to start somewhere.
