¿Sure? OMG!! Thanks a lot!!
Ey @aitpro! THanks for posting. Yes, sounds to be that. Hope you find the solution. I will do the same.
thanks! 🙂
I have the same issue. I updated to wordpress 4.7 and lost settings and capabilities from my admin users. All are keymaster.
I created a new admin account and they has all privileges and capabilities. Tabs (Forums, Replies, etc.) are back for this account but not in others.
