Hmm, it appears that Monster Insights WordPress Plugin updated itself at some point with a bug in it and took out my whole wordpress site. All pages just responded with a page saying that a Critical WordPress Error has Occurred. Gulp. I guess that’s probably better than a raw php error though.
Anyway, the fix was to remove the plugin’s directory in the WordPress plugins directory and then delete and reinstall the plugin. Annoying? yep, but not too big a deal in the grand scheme of things.
Ironically, I probably wouldn’t have noticed the problem until the next time I wanted to post, except the IFTTT pipe I use to syndicate reported that my WordPress install wasn’t reachable. Nice! I should probably figure out how to add some monitoring.
