If you’re reading this you would have noticed I’m having problems with my WordPress and I had a Catchable Fatal Error. It’s now on the path to recovery. The issue has been rectified - but not resolved. The problem started after I relied too much on Softaculous which is used by my hosting provider to update all my WordPress sites.
So always keep a backup and a backup of that backup - it makes life easier to recover from.
But at the end - it was a problem with a plugin conflict which was corrupting everything after I tried to edit existing posts. Lesson learned! Keep good backups and don’t do stupid things to plugins.
