I've disabled IP validation, since I may need to login to my admin account from elsewhere.
And yes, I DID ban myself. I logged out since I wanted to see what guests would see, but I didn't close the tab at the admin URL. Then while logged out, I refreshed my admin tab, which probably triggered my firewall, but it didn't block me yet, then when the admin section prompted me to enter my password, I entered it incorrectly, then the firewall blocked me.
You say that what I did won't remove my IP from the block list, but then why do I have access to my website again, even with the firewall enabled?
