the group booking screen is displaying "BILLING INFORMATION" above the contact details. This is confusing people booking on our free events. Can this title be edited or removed manually?
That is the default text to show on the final group contact page as it is usually a billing person also. You can change it, like any other text, in the language file:
/language/en-GB/en-GB.com_dtregister.ini
Search for this text and modify as needed. You could event leave it blank (after the = sign) if you don't want any text label there.
We shouldn't have to hack the language file to solve this problem. The system should know when an event is free and should automatically change the title from "Billing Information" to "Contact Information."
