I have a similar issue. I have just installed the plugin and am running tests, but the plugin does not seem to be working.
I am not using the limited registrations add-in. But I have selected to block all free email domains. However, I am still able to register an account using a blocked domain (mailinator.com).
I have checked “Do not verify client IP address” during testing (as recommended by the help documentation).
According the to the plugin admin page, I have a valid API key and the WangGuard server connectivity status page says WangGuard servers are available.
I am not sure how to proceed.
Thanks for your help.
