Im running a WP with multisites option enabled, now im trying to create some users and give them privileges over different sites but in the dropdown menu of each blog the roles are missing, as you can see in this screenshot http://cl.ly/3N7A
What can be happening here? Some missing configuration?
I dont really know what to do, been working with WP for some time now and never seen something like this happening.
Thanks in advance for your help.
