Hi Zach,
Thanks for reaching out.
You are already using the Pro and you don’t need to activate the Cornerstone plugin as it is already included in it. And if the issue is related to the Cornerstone, it will affect the whole site.
I suspect it might be something else which is behind your problem. I would like to suggest troubleshooting the following common issue to help us to recognize the reason.
1.Theme Related Issue
2.Plugin Conflict
3.Theme Update related issue
4.CSS/JS Customization
5.Disabling Cache
6.Disabling CDN
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
– FTP/CPanel credentials to access the files.
To create a secure note, click the key icon underneath any of your posts.
Thanks
