Hello,
This is unfortunately a known issue that we are working on getting resolved. In the meantime, we do have a workaround.
Following the instructions in our themer’s guide, you can do a template override of the orders-edit-meta.php template found at wp-content/plugins/event-tickets-plus/src/views/tickets-plus. You’ll want to paste this code into your copy.
I’m sorry for the inconvenience, but I hope this helps get things up and running until we can release a fix. I linked this thread to our internal ticket for this issue – as soon as we have an update, we’ll let you know here.
Thanks,
Jennifer
