Regretfully we can not provide you a specific IP because most of us are in dynamic IP, we can not provide a IP range either because we are from different parts of the world, and we do not know who's going to handle your thread next.
Your Content Builder (Cornerstone) is acting as standalone because it does not detect that you're using PRO. The real PRO panel is the one on the top, the one in the bottom will be gone when we resolve the real issue.
Refrain from using Appearance > Customize, because we are kind of going away from that. Get used to the PRO > Theme Options
After we resolve all of this the Custom CSS area will be on PRO > Theme Options > CSS.
Of course you can also put custom CSS on the native Wordpress CSS area that is the Appearance > Customize > Additional CSS.
So here is your real issue:
You rename your PRO folder to
pro-1.1.1 please login to your server via FTP or cPanel and rename that folder back to just
After you rename the folder login back to your admin dashboard and re-activate the PRO theme (Appearance > Themes)
The second issue is your PRO version 1.1.1 is kind of outdated, please update to the latest PRO version 2.0.1.
Updating Your Themes and Plugins
Remember to clear all caches (plugin, server-side, CDN, and browser's cache) after updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Hope that helps,
