Hello,
I was using the wordpress SEO by Yoast. I deactivated that as well as all of my plugins and reverted back to the default wordpress theme and the plugin worked. I’m currently using the vantage wordpress theme. I also started re-activating my plugins and then would test the registration form and it still worked! The only plugin I have not re-activated is SEO Yoast. Does that plugin interfere with your plugin? Thank you for your time and response.
Best,
Philip
