1.3.0 bug after checkout confirmation?

Hello Tuan,

Thanks for all the work for version 1.3.0. I installed it and I am testing the version at the moment.

I found out something goes wrong. Here it is.
I have multiple events on YES. When I select an event and fill in my personal data and then click checkout confirmation out I get the message : "There are no events for processing checkout. Please choose events for your registration' and then I go back to the events view. However the selected event is shown in the page with the Selected Events text at the top.

Any idea what might be wrong?

Kind regards,
Marcel

I just found out that this occurs when in the configuration:
Integration is set to NO INTEGRATION and User registration integration is set to YES.

Regards,
Marcel
