This site has used paypal buttons/IPN with s2member successfully for several years.
I’ve recently moved the site to a new host, and added a new paypal button, for a new subscription option.
Now users who click the button, successfully pay via paypal, and are redirected back to the site, get the login form (http://www.navsa.org/wp-login.php?action=register), with “User registration is currently not allowed”.
If paypal IPN payments are working correctly, originating from an s2member shortcode-generated button on the website, and users are getting emails with links to return to the site, why would they be presented with “Registration is not currently allowed”?
If I am logged in to the WP dashboard as an admin, and I visit the link they get from paypal, I get the registration form correctly, and can complete their registration for them. Any help would be much appreciated.
