Thanks, the issue indeed was that the client IP address was detected incorrectly, so I was blacklisting the proxy servers connecting to my site, not the actual clients. I was blocked from logging in because my request went through a proxy that I had blacklisted.

The solution was to go to the Loginizer Dashboard and change the IP detection Method to “Custom” and “CF-Connecting-IP”. The other methods all returned the proxy server’s IP address rather than my client’s.

I had read the instructions for configuring Loginizer, and I don’t remember coming across an explanation of how to correctly set the IP detection Method (but I was drinking from the fire hose at the time, a lot to learn). If it is there, perhaps it’s not prominent enough in the documentation?

About logging in via the Softaculous WordPress Manager app: note that this also does not work for the same reason (IP of proxy was blacklisted). The only workaround was to disable Loginizer by renaming the directory. Also note that just renaming the directory after successful login does not work: I found the plugin deactivated and also had to reactivate it from the WP -> Plugins page.

I like the plugin though, it’s adequate, simple and does the job (so far at least).

Cheers.
