Hi, I bought Pro and Cornerstone and when I try to activate Cornerstone after installing it, I get this error:
Fatal error: Cannot declare class Cornerstone_Plugin_Base, because the name is already in use in /srv/bindings/ed3316935fbd4972bce4fbe9a51c297c/code/wp-content/plugins/cornerstone/includes/utility/plugin-base.php on line 6
