Dear Team,
I am very much a novice. I have installed Wordpress and have installed X Pro. In my plugins I see Cornerstone but when i try to activate it I get the following:
Fatal error: Cannot redeclare class Cornerstone_Plugin_Base in /var/sites/w/wpstage.pprussellsquare.com/public_html/wp-content/plugins/cornerstone/includes/utility/plugin-base.php on line 6
Please advise.
