Hi, Amy. Sorry you’re experiencing this. Do you think this is specific to X Theme? If yes, did you try switching skins and see if it works with a different skin (users have previously reported some skins cause more troubles than others)?
I visited your site and see that it’s rendering events but they’re below the navigation, which I found odd.
Anyway, I noticed console errors at your site: https://cl.ly/3Q293z0A2b1Q
(If needed, you may reference our KB article Using Google Chrome Developer Tools.) They should be fixed.
I’d also suggest you enable WP_DEBUG and WP_DEBUG_LOG and share any debug messages you see while navigating your site’s home page, events page, single-event pages, and any other of your site’s pages relevant to this ticket.
Please let me know what you discover, and I’ll do my best to help further.
