The simpler media website CMS
The plugin "IP Blocker" is enabled, with 6 IPs originating in Russia blocked.
The security log shows 2 attempted admin logins using random user names every 6-7 minutes (hundreds of times in total over the last few days), with all attempts originating from 2 of the 6 blocked IPs. Logon threshold and cool-off are set also, but seem equally without effect.
Any idea why the IP Blocker plugin might not be working as intended?
