Hi alexrothewell,
I think there might be a problem with your jquery version.
Check this screenshot that I take inspecting your site:

Maybe this is cause by a plugin installed.
You can try deactivate all the plugins and start activating one by one, checking after each activation if the problem remains.
If a plugin causes the problem, and you really want to stay with that plugin, you can try by installing another plugin that helps you keep jquery version updated. I didn´t use these plugins but you can give it a try!
Here you can find 2 options:

https://ww.wp.xz.cn/plugins/use-jquery-cdn/
Let me know if this works!
Thank you so much! The jquery updater plugin worked fantastically! Can’t thank you enough!
Great! I´m happy to helped you out!
Mark this topic as resolved please 😉
