I resolved it. It was the Messages menu that was disabled, but in my case there was a duplicate menu with the same link and that caused the conflict.
I had to remove the duplicate menu that was disabled.
I had this problem as well, it is caused by changes inside the customize skin menu. I'm not sure what kind of change causes this issue exactly, but using the button 'RESET TO DEFAULTS' solves this issue.This problem is happening to me also.
I never changed the Messages Menu before.
Has anyone found a way to resolve this?
Logged in as admin, but cannot access the messages. It says "This feature has been disabled. Please, contact your administrator."
How/Where to enable messages?
Try using the 'RESET TO DEFAULTS' button, like I described above here.same problem here. I don't have any customization on evo skin.
