why are my pro sites showing blank pages?

not sure if this is beacuse im not totally finished setting up pro sites or if there is an actual issue currently with the plugin since the premium plugin part doesnt seem to be working.

when i got to my test domain and click on the prosites up grade tab im taken to a blank page.

also i set the levels for premium plugins but the “premium” plugins are still showing up in my “free” test sub-domain.

so is there currently an issue with the plugin or am i missing something? because if i set my test subdomain to the free plan but made my premium plugin for…lets say level 1…than the “free” subdomain shouldnt have access to it any longer…correct? only it still does…oh and not sure if this helps…but the plugin is also not network activated…please help…ima noob
