Hi Daniel!
I’m sorry you are also experiencing the same issue.
It seems the other user was using an outdated version of The Events Calendar, which was causing the issue. I can see from your system information that you are using the latest versions of our plugins. Are you still experiencing this issue?
If you are, please go through the testing for conflicts guide to narrow the problem down > https://theeventscalendar.com/knowledgebase/testing-for-conflicts/ and let us know what you find in the process.
Let me know how that goes.
Thanks,
Victor
