Hi @100leiden,
Thanks for reaching out.
I have cheked your website and found the problem you have described here. I would suggest you do deactivate and delete the Pro and reinstall it by downloading from your Themeco Account once again. After you reinstall the Pro, please check once by clearing all types of cache including the Style Cache from Cornerstone > Settings > System > Clear Style Cache and check in the incognito/private mode of the browser.
If that does not help, 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.
NOTE: Please confirm if the existing setup is your staging server.
Thanks
