After upgrading our church's DTRegister component from 2.7.4 to 2.7.18a we get this error on all of our registration pages:
Warning: Invalid argument supplied for foreach() in /PATHTOOURFILES/administrator/components/com_dtregister/models/event.php on line 670
Any insight would be appreciated. This error displays on each registration page but registration is still allowed. However after the last step it goes to our home page rather than a confirmation page.
