WordPress Membership Plugin
It look like it is a theme conflict issues. I change to default WP theme and it now can register.
But problem is the theme of my website is made by our former developer and we can’t contact him anymore. And I’m a new guy here (also a WordPress newbie) I’m not sure where to start looking. Do you have any advise of where to start looking inside your plugin? like which file that relate to register process so I can continue troubleshoot.
Thank you so much.
