You may want to remove the option to purchase a specific ticket, but cannot delete it because individuals have already purchased those sort of tickets. Wizevents provide the ability to remove the ticket from display for the future.
How to get there:
Login to the Wizadjournal admin backend.
Click on the menu tab "Registration".
Click on the first icon, "edit".
What to do:
On the right hand side, under the "Ticket Types" category, locate the ticket you'd like to edit.
Click on the pencil icon, "edit" adjacent to the ticket name that you would like to change.
Click the checkbox next to "Hide Ticket".
Click "Save Session Ticket Type Changes" to complete the process.
