Hi folks,

Registrants seem to be getting an error if they go through the event reg and then hit on their back button to make changes to their info. Any help would be great.

Debugging returned the following:

Hi, yes, I created a Greg's Test Event at http://joomla.demo.civicrm.org/index.php?option=com_civicrm&task=civicrm/event/info&id=5&action=preview&reset=1&Itemid=55
and ran into the same issue.

Once you get to the Thank you page, press the back button on your browser.

You should receive the non-recoverable error message.

Thanks,
