Hello Bea!
Thanks for reaching out to us! 🙂
I’m sorry you are experiencing that. Let me help you with that.
By the look of the screen in the screenshot you sent us, that might be some Javascript error.
First, you should make sure you are using the latest versions of our plugins and the WordPress core.
If you have the latest versions and the issue still persists, this could be related to a plugin or theme conflict, so please go through the complete steps in this guide > https://theeventscalendar.com/knowledgebase/testing-for-conflicts/ and see what you find in the process.
When coming back, please make sure you share with us your latest system info by following this guide > https://theeventscalendar.com/knowledgebase/sharing-sys-info/
Let us know how that goes and if you have any questions in the meantime.
Thanks,
Victor
