Hey Aaron,
first of all, thank you for the purchase!
The Shogun theme already has the latest version of the Visual Composer plugin – the one by WPBakery – integrated into it (with additional styling and block options). As far as I understood, you are trying to install the VC plugin separately on top of the theme – is there a specific reason for that? Please let me know if I understood you correctly.
Sincerely,
Andrii / Satori Studio
