Hi Ursula!
Thanks for reaching out to us!
I’m sorry you are experiencing this issue 🙁
I could not reproduce it on my own local installation, but I can see from your site that the ics export file is empty. Let me help you troubleshoot that.
This could be related to a plugin or theme conflict, so to narrow the problem down, could you please go through the complete steps in this guide > https://theeventscalendar.com/knowledgebase/testing-for-conflicts/ and let me know what you can find in the process?
Also, could you please share with us your system info by following this guide > https://theeventscalendar.com/knowledgebase/sharing-sys-info/
Thanks,
Victor
