Welcome back, Mandy 🙂
In order to use Event Tickets Plus, you will also need to have Event Tickets installed and activated. Event Tickets Plus uses the same base code included with Event Tickets, but adds on E-Commerce functionality.
I hope this answers your question and the next time you need information about products you’re considering purchasing, please post over at our Pre-Sales Questions support forum.
Take care and let me know if you have any additional questions. Cheers!
