I just installed a clean version 4.7.10 and no other apps except the Younet Advanced MarketPlace which resulted in an error 500, no users, minimal load. So decided to try it again on a differenct dev server, same thing.
Can anybody else, assuming there is somebody else, test this in their dev environment. I know they will ask for my admin creds, which I do not give out. They should try it in their dev environment.
