Hi Jason!
I’m sorry you are experiencing that. Let me help you with the troubleshooting.
First, could you please share with us your system information by following this guide > https://theeventscalendar.com/knowledgebase/sharing-sys-info/ ? We’ll see if there is anything strange that would indicate an error from there.
Do you recall making a recent change in your site, like a theme or plugin update? or probably installed a new plugin?
To make sure we are not dealing with a theme or plugin conflict, and to narrow the problem down please go through the steps provided in the testing for conflicts guide > https://theeventscalendar.com/knowledgebase/testing-for-conflicts/ and let us know what you find in the process.
Thanks,
Victor
