Hello Darren,
Thanks for writing to us.
I checked your site, it seems that there is some JS console error on your site. It might be because of the plugin conflict or the custom JS/CSS customization issue. Please have a look at the screenshot in the secure note.
I would suggest you troubleshoot with a few of the common issues before we investigate your settings.
- Testing for Plugin Conflict
- CSS/JS Customization
- Version Compatibility
- Disabling Cache
- Child Theme
If none of those work, It would be best if you could copying your live website to your staging area. and send your details in a secure note so that we can investigate your setting without breaking your live site. Please provide the following details
- WordPress Login URL
- Admin level username and password
You can find the Secure Note button at the bottom of your posts
Thanks
