Hi James,
Thanks for using our plugins, let’s see if we can get you squared away here!
For some reason your calendar is outputting with the mobile layout styles. Are you by chance minifying the CSS on your site? It’s possible it’s a conflict caused by that process.
Also, I noticed you have a caching plugin installed. Just for good measure, would you clear the cache and see if that has any impact? Sometimes that causes the weirdest issues.
Let me know what happens with those steps, and we’ll work from there!
Best,
Shelby 🙂
