Hi Lucian, thanks for your quick reply! Unfortunately I don’t know what version it was on previously. The plugins page had automatic updates enabled, but i’m not sure how often that happens. I would guess it was on the previous release assuming the auto-updates happens frequently. Let me know if there’s a way I can check better on this – the site is on WPEngine.

The site is a single site. For some users they were still able to reach the site and pages, but for other users they were seeing critical WordPress errors failure page. Anyone who tried to reach the admin page would get the critical WordPress error page, and were unable to do anything. We brought the site back online by seeing the logs and then renaming the plugin folder on disk so it would stop loading. We then disabled it from there as a short-term fix.

Here is the full error log with the website name removed:
