Hi Sean,
I’m sorry you have a problem with the datepicker. Let me try to help you.
Unfortunately I cannot get to your site, it shows Maintenance mode. Can you make it accessible for me?
Meanwhile please provide me also your system information, here’s a guide how to do that. https://theeventscalendar.com/knowledgebase/sharing-sys-info/
Also, this might be caused by a conflicting plugin or theme. Can you please follow our testing for conflicts guide: https://theeventscalendar.com/knowledgebase/testing-for-conflicts/
Let’s see if that can narrow down the cause of this.
Cheers,
Andras
