Cornerstone fatal error triggered

[whitecrow7]

Trying to use cornerstone but it gave me a fatal error. How do I fix this?

Plugin could not be activated because it triggered a fatal error .

Fatal error : Cannot declare class Cornerstone_Plugin_Base, because the name is already in use in /home/smilingb/public_html/wp-content/plugins/cornerstone/includes/utility/plugin-base.php on line 6

Hi @whitecrow7,

Thanks for reaching out.

You have a Pro theme in which the cornerstone is already built-in. You don’t need to activate your cornerstone

Thanks!
