I’ve just installed x pro. Before I had x theme. In the normal version of the theme I can use cornerstone, but trying to use it in x pro tells me this error when I activate it:
The plugin can not be activated because it generates a fatal error.
Fatal error: Can not redeclare class Cornerstone_Plugin_Base in /home/tellmeno/public_html/wp-content/plugins/cornerstone/includes/utility/plugin-base.php on line 6
