TOPIC: Warning: Invalid argument supplied for foreach()

I have Multiple Event Cart Option enabled and after registering for an event if I click Register for another event I get the following error:

/home/gbr/public_html/register/administrator/components/com_dtregister/models/event.php on line 746

I also cannot view the cart after registering. It takes me to this url, /index.php?option=com_dtregister&Itemid=0, which just shows the homepage.

Any ideas?

Oops forgot.

DT Register: v2.8
Joomla: v2.5.6

I am running PHP version 5.315 could this have anything to do with the issue?

I have had the same issue.
- Joomla 2.5.6 (when this error occurred)
- PHP 5.2
- DTregister 2.8.0

We had a user (running Safari) go to register for a second event before checking out, and the following error dump occurred:

After restarting registration, the cart seems to contain both events.
Subsequent pages like the credit card payment form seemed to have the css messed up, but this could have been due to the spewed warning messages.

Experiencing a similar issue here during registration, I just submitted a support ticket but am also bumping this thread in case any of you found easy solutions!

I was able to get most of my issues resolved through support tickets, but sometimes takes a day or 2 to get a response.
