Hi Fraser,
Thanks for using our plugins and for reaching out with that issue!
I checked your site and it looks as if your theme had a setting for this. The events are there in the code, but they are hidden with CSS. Please check your theme’s settings if you can find anything like that.
To make sure that your events are showing and that our plugins are working as expected, you can switch to a default theme like twentysixteen or twentyseventeen and check your events page there.
Let me know what you find.
Cheers,
Andras
