The Development Data Entry system role does not have rights to see the Tribute tab. 

If a user needs the rights to Tribute, please assign them the Annual Fund Manager system role.  

If a user has Annual Fund Manager and Development Data Entry, Development Data Entry is currently preventing the user from accessing the Tribute tab.  If a user has Director of Development, Development Data Entry, and Annual Fund Manager, then remove Development Data Entry system role.

Once you have removed the Development Data Entry role, log out of Altru, close your browers, and log back into Altru for the new security roles to be activated.
