Good evening Robert and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the monthly view no longer working on your site.
I would love to help you with this topic.
By the looks of it, there is a Javascript error being generated on https://www.myfathersmustache.com/events-charleston/. You can see that in the Google Developer tools console.
More specifically, the error comes from https://www.myfathersmustache.com/wp-content/themes/mfm/js/sticky.js?ver=4.8.2
One solution could be to dequeue that specific script from the post-type-archive-tribe_events pages: https://gist.github.com/elimn/e302522579650914e03048ebed146854 or to dequeue that script altogether.
But before you do any of that, it looks like you are not using the latest version of our plugins. I would recommend updating both the Events Calendar and the Events Calendar Pro to the latest version in case that helps.
Let me know how that goes.
Best regards,
Geoff B.
