Sorry for the delay in replying. Seems like in this order customer was added a wrong ticket than the one they purchased.

Are you still experiencing this ticket over sold issue? As artem mentioned, it may be the auto complete regardless of payment status causing this?
Yes,
it worked for me.
“Some issues are like a needle in haystack”
that’s exactly what i thought about this issue.
Thanks
In fact if you are using custom repeats it should show a notice at the current version of tickets addon. We will make this more prominent

Thank you for your kind input we will be sure to include warning notices in the future when customers are making edits to repeats after tickets are sold. If you have more questions, kindly send us a new ticket and we would be more than happy to help you resolve your issues!
Sorry for the delay John. Where can I see this issue? the eventon account no longer have access to my account.

I think this avada theme is adding bunch of things unnecessarily. Are you able to send FTP access to your site so I can check whats going on?
Currently, the subscriber has pluggable filters in place to allow admin side event publish to run emailing function. ActionUser compatibility is not a feature we have advertised. https://www.myeventon.com/addons/subscriber/
We will add the actionUser support in the coming updates to subscriber 🙂
