Kaltura CE latest version 11.1.0 blank central screen (menus are shown) in KMC after login and also API -1 Error in KAC

Hello,

you are login into kmc with the admin console user
that is not correct

you should login using yoursite.com/admin_console

then create a new partner and now you can go to yoursite.com/kmc
and now login with that partner
