Manage Registrants from Frontend

When I linked in a menu field the event booking link to manage registrants in the frontend i saw "HTTP ERROR 500" the evetn booking version isn't the latest but is the 3.0.3.
The automatic link that i connect thi menú: index.php?option=com_eventbooking&view=registrants

Hi Riccardo

Maybe it's because that very outdated version of the extension is not compatible with Joomla version you are using

Better update your site to latest version of Events Booking and try again. If the error still happens, please submit a support ticket so that we can help checking and solving that issue
