Commands working fine Either an issue with your RBAC, or account security settings.
EDIT: For reference sake, there's always more information to give, which would normally lead you to what the issue is. Have you set up RBAC correctly? Have you set your account to a GM account? Is your database up to date? So on and so forth.
As shown in my previous post, it's not an issue with the source, it's working perfectly fine with a fresh source, fresh compile, fresh database and an admin account. Has to be something on your side
Do you use custom GM ranks? Cause GM level 4, as you are using in your account_access table isn't a valid GM level 0 is player, 1 is Mod, 2 is GM and 3 is Admin. I bet you if you change your account_access GM level to 3 it'll work If not, you'll have to add a row to rbac_default_permission with secId = 4 and permissionId = 192
Eluna itself has nothing to do with RBAC. We do have a 'reload eluna' command, but that doesn't effect your commands not working. If you have an issue with RBAC, that's probably because you don't have your account permissions setup in rbac_account_permissions table. There's also known issues with RBAC where commands don't work if you restart your worldserver but not your authserver too.
