I have the "Enable User Registration email confirmation" setting set to "No", but each new user still can't login without first clicking a link in a verification email. Does anyone know why this would be occurring?
After a little more investigation, I discovered that this is due to using reCAPTCHA in WordFence's Login Security. It's designed to use the WordPress default login flow, which WPForo apparently doesn't use. Has anyone encountered this or know a way around this other than to disable reCAPTCHA in WordFence?
But Wordpress anyway asks for mail verification ....
registration is turned off, so users are only being added manually.
Your question is not related with wpForo.
If you have disabled registration in wpForo and want to create users manually, you need to do this within the WordPress Dashboard. The manual user creation process is handled by WordPress itself, and wpForo does not perform any specific processes when users are added manually. You can use the standard user creation functionality provided by WordPress for this purpose.
