wp-admin issue

Hello.

I downloaded Cerber for evaluation purposes. I tried to follow some of the recommended settings here.

But my wp-admin page became unavailable to me. I had to get my web host to deactivate Cerber so I could get back in.

Is there one or more of the particular settings that might have caused this? I don’t remember selecting “please make it so I cannot use my wp-admin page” !!
