On my Joomla site, I use Joomla/Hikashop/Moodle. I only have one field for name "Name" and when the user inputs both First Last name in that single field it is automatically separated into First Last on the back end for Hikashop and Moodle. By having the extra Last Name field in Easy Profile it duplicates the last name, however, I am not able to unpublish the Last Name field in Easy Profile. How can I resolve this?
