Hi Jeroen
Thanks for reaching out.
It seems that the minification of the CSS code might be the reason behind it. I would suggest you temporarily disable the minification and check if that works for you.
If that does not works for you, I would suggest you troubleshot a few common issues to recognize the actual reason.
1.Plugin Conflict
2.Theme Update related issue
3.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 that does not help, please provide login credentials for your site in a secure note to examine it further, including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
To create a secure note, click the key icon underneath any of your posts.
Please note that a few hours ago we have released another version of the theme with some fixes, I would recommend you to update your theme to the latest one.
Thanks
