I did not update any plugins or themes and my host did not make any changes to the server.
However, I am on auto-updates for WordPress through my host. I’m running 5.7.1. on WordPress and 4.4.7 of this plugin. Reading through the change log, it looks like that might be the issue, but I haven’t tested that yet.
Thanks
I disabled the plugin via file manager and I’m back in but I still don’t know what caused the problem in the first place.
