Only lost one post. I recently migrated off Dreamhost to a FreeBSD server on Linode. Last night I was doing routine updates from the bar and broke MySQL somehow. Then I tried installing mariadb instead and lol shitshow.
FreeBSD users: DO NOT INSTALL MARIADB103. IT’S B0RKED. USE MARIADB102.
Also, maybe do a mysqldump after every wordpress update. Good practice.
