Do you have guide or instructions for running BPSPro on Subdomain based Multi-site Network with Domain mapping plugin? Any links or articles on how to configure and all.
As far as I know BPS Pro just works with the WordPress MU Domain Mapping plugin and the WPMUDEV Domain Mapping plugin and nothing special is needed. Are you running into some sort of a problem?
BPS Pro does not do anything with Super Admin User Roles or Administrator permissions regarding site restrictions/limitations/accessibility. BPS Pro does check User Roles in order to load specific things in the BPS Pro plugin itself, but those checks/conditions do not affect/restrict/limit anything about your website. It sounds like the problem is that you are missing code in your wp-config.php file for a Network/Multisite site or the code in your wp-config.php file is not correct/valid.
