Ban Hammer doesn’t do IPs. Never has, never will. It’s for stopping emails from registering.
You asked “Does this work on 3.8” of Ban Hammer. Answer: yes, MY plugin does. I’m using it right now. Even went and installed on a new WP instance to verify and checked with WP_DEBUG on. No errors ??
wordpress-ip-address-blocker-pro isn’t my plugin, either, and I’ve never used it, so again, not really anything to do with me or my plugin.
Unless you’ve got an error with my plugin, or a question about Ban Hammer, there’s not much more to say. Slinging random comments like how plugin devs are slacking is demoralizing, and not a nice way to get people to help you out. Most plugins that were working on 3.7 work on 3.8.
