Eventbooking changes the domain during reg process

Hello,

I'm having a problem with what appears to be Event Booking changing the domain name from .com to .info after users hit "Register Individual" and thus causing a SSL cert mis-match which stops most users from continuing to the Registration Confirmation page. You can see this at: www.ag4sc.com/index.php/events?task=view_event&event_id=8

Any idea to why this is happening? It seems that the link on the register button is getting generated wrong for some reason. Any help on this would be greatly appreciated!

Also I failed to observe correctly that it happens either at the initial clicking of Register or after the form is filled out and when the users clicks Registration Confirmation. This also results in an invalid token error.

I just checked it on your site and didn't see the error like you said ?
