The cert renewal service not only didn't run, it's not even installed! I've manually renewed the cert and it's looking good now, and I'll get that service running when I'm in front of a proper computer. Thank you again!

Womp-womp. Looks like a table got corrupted. Luckily fixing it was easy. This is why we take backups!

Oh, and thank you!

Yep. Back up now. I'll take a look at the logs for repeat offenders.

The database is really memory hungry, especially with overseas bots constantly attacking the site. It used all the server's memory and forced the kernel to kill the php-fpm daemon. I started it back up, and now the forum is back on. Thank you for the heads up. I need to automate this...
