Hi,
Easy Profile is not designed to add registration form in another static page****, your template override add a static registration for in Joomla Login page.
For example in your site:
-
https://your-domain/index.php?option=com_users this link should show only login page (not registration form)
-
https://your-domain//index.php?option=com_users&view=registration this is correct Joomla registration link
You should remove template override by rename (or delete) folder at /templates/gk_events/html/com_users/login to /templates/gk_events/html/com_users/login.old
**** Easy Profile extends Joomla user management (not replace), so registration and edit profile pages are the same of Joomla. Your override add a static form near login form, but this form not load Joomla Users Plugins (so Easy Profile basically does not do nothing ).
