Hi There @istandard
Thanks for writing in! Upon checking your site, I see that you’re using a Pro beta theme. I would suggest you to check your issue with Pro stable version (https://theme.co/changelog/). You can simply delete (backup) your current theme and install the stable version of Pro and all the current settings will be saved in the database.
Also you need to check the WordPress version running on your site. You can check the latest version number from here (https://wordpress.org/download/) and update accordingly if needed (https://codex.wordpress.org/Upgrading_WordPress).
If you’re still having issues, you need to disable your 3rd party plugins except Modern Events Calendar to see if there’s any plugin conflict. If the issue is resolved, then you can activate your plugins one by one to see which plugin causing the issue.
In case if you cannot isolate the issue, provide us with your WordPress login credentials along with your FTP credentials in a secure note to check your issue further.
Thanks!
