Thanks for informing that WP-Members only adds captcha to registration. Is there a way to include that information on the settings page to avoid confusion?
I’m using another captcha for my contact form, though that wasn’t the conflict.
It turned out to be settings in “iControlWP” Shield. I simply turned off “Login Protection”, emptied cache and all works well. I’ll be turning settings in that module back on until I find the exact problem setting.
Thanks for your help!
