Hello Kenneth,
Thanks for reaching out! Do be able to give you full suppport, please open a new thread and reference this one.
Please check if your theme, WordPress and plugins – especially the Modern Tribe ones – are updated.
Also I would like to ask you to
1) give us some details on the issue at hand;
2) share your system information with us and
3) if you could attach some screenshots on how the event is set up, that would be most helpful.
This way we can give you dedicated support.
Thanks and looking forward to receiving your thread!
Cheers,
Andras
