Good evening Adam and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear that you are struggling to get the calendar to display with your theme.
I would love to help you with this topic.
The first thing I would recommend is trying different settings forĀ Events Template underĀ Events -> Settings -> Display.
If that does not work.
Could you please send me a copy of the latest version of your WordPress theme / child theme via a link to a .zip file link (stored Dropbox or Google Drive) so that I can run some tests on my end ? I recommend a private reply for that purpose.
Please ensure you are using the latest files as found on your actual website.
This way I will get access to any updates or customizations you might have made.
Hang in there!
Geoff B.
