Today suddenly encountered the ‘Critical Error’ notice on two of my websites – both are running on the same server, and both are running outdated WP installations (v 5.5.13). No recent changes to the websites.
What I’ve done so far: Deactivated plugins. Opened wp-config and enabled debugging.
I cannot make sense of the debugging log. Can anyone here explain it to me?
I actually suspect that there might have been a recent PHP upgrade on the server (it’s shared hosting), and possibly this could have affected it?
