What I discovered was that this plugin changed where/what CF rule to make. In the pas it used one of 3 CF rules. CF added other sub-type o f rules and so now it isn’t using up 3rd rule [free CF accounts and I typically make 2 rules to redirect www to https and http to https] .

The update of this plugin didn’t clean up the 3rd rule so some issues arose from that. Perhaps it duplicated it in the sub-rule tab and hence the notifications and issues.

I tried all possible things including wasting tons of time deactivating/reactivatng plugins to no avail.

ONLY SOLUTION was uninstalling it and reinstalling fresh – without any saved settings.

And then re-applying my settings (after reconnecting to CF and the CF site.)

NOTE: If you forget to set in this plugin to not save plugin’s settings on deactivation, you’ll end up needing to clean out all tables and options in DB before re-installing it again!

A clean installation of an older version from 2 weeks ago and everything works again.

I initially tried rolling back via the link the plugin provides but nothing functioned.

It was bizarre since it defied logic.
The older version had functioned perfectly well.
So that’s when I noticed the issue with rules in CF.
The v5 changed the location of CF cache-all rule, and rolling back didn’t support this.

You MUST delete all plugin saved data and reinstall the older version prior to 5.

I FTP’ed the backup of it to the WP plugins folder on my server.

If you have no older saved backup, you need to mend your ways and back up stuff on a regular basis… for events like this may occur again. Some plugin will sooner or later f* something up. One must have backups and then all is not lost.

Additionally, from now on, my live sites I’ll never again enable auto-updates.
Use WP Staging plugin to test before pushing to live site anything.

Will take my time before updating to the v5, lol, even dev says he made a fix.
Probably gonna be coming up with lots of nasty nags and service ads.
