Hi!
i have been stuck in this problem since a week. Mainly all users by defult are admins. I only have administrator role so that:
1- i created a developer role& permission
2- i added users to the Developers role and project to Developers permission.
3- I gave login access to the Developers
4- i gave only one permission to the developers which is adding comments. and all other permissions for the administrator. Just for testing.
5- I removed users from other groups and roles. They are only exist in Developers role.
After all that still Developers users have same permissions for administrators !!! what can i do more pelase help!
