Hi. Sorry you’re experiencing this.
I see your Event Tickets Plus isn’t at the latest version. Could you please make sure all your Modern Tribe plugins are at their latest versions?
Once you verify you’re on the latest versions, please test to see if the issue is still happening for you.
If it is, please follow our Testing for Conflicts Guide and see if that helps narrow down the cause of this.
If it doesn’t, please share your System Information. That will give me a lot of extra information to help diagnose the problem.
Let us know what you find out.
Thanks.
