vladax on "[Plugin: All In One WP Security & Firewall] Strange user lockdown"

I see my IP in the Currently Locked Out IP Address Ranges list although I have never entered bad password.

If I click on Unlock or Delete I get an error:
Warning: call_user_func() expects parameter 1 to be a valid callback, second array member is not a valid method in .../wp-content/plugins/all-in-one-wp-security-and-firewall/admin/wp-security-user-login-menu.php on line 61
