Hi Patrick,
I have checked your website and found the issue you are describing, there might be some different reason behind your reason. I would like to suggest troubleshoot the following common issue even if you have done this before it will help us to recognize the reason.
1.Plugin Conflict
2.Theme Update related issue
3.Child Theme Related issue
4.CSS/JS Customization
If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.
If none of the above helps, please copy your live site to a staging server so we could troubleshoot freely without breaking your live site.
And give us access in the secure note including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
To create a secure note, click the key icon underneath any of your posts.
Thanks
