Hello,
If you’re having issues with Events Aggregator, please create a support ticket and we’d be happy to help troubleshoot for solutions. The Facebook Importer plugin is no longer available as it’s been replaced with Events Aggregator.
In response to the QR question, please review Tickets: Managing your orders and attendees as it contains detailed information on how to set up and check in tickets using a QR scanning app. If you need specific instruction, please create a support thread as we are unable to provide support through the Pre-Sales Channel.
You can also hide/add images to your tickets, emails, etc. using the instructions outlined in our Themer’s Guide. Again, this is a topic you’ll need to create within the necessary support forums.
I hope this helps and have a great Friday. Cheers!
