IP blocking not working

Hi.

I have what should be the most up to date version of Loginizer. I am getting email notifications of multiple attempts to log into the site from the same IPs via Sucuri, despite my having added those IPs to the blacklist previously, and they have continued despite exceeding the maximum number of tries before lockout I have set via Loginizer. In fact, Lognizer hasn’t even registered the failed attempts.

ie, the blacklist isn’t blocking the IPs listed, and Loginizer isn’t working to lock them out despite multiple failed attempts.
