Error Installing Uncode-Core Plugin

Hi there,

I'm trying to install the UNCODE theme, I've uploaded the theme fine, but when I go to add the plugins I get an error because of the "Uncode-Core" plugin.

The error reads...

Fatal error: Call to undefined function vc_editor_set_post_types() in /home/foldername/public_html/wp-content/plugins/uncode-core/vc_extend/init.php on line 10

Line 10 of the PHP file is: vc_editor_set_post_types( $list );
