Hey i tryied to put hidden manager on my page and its not working, It's saying- [TR="class: _51mx"] We weren't able to add all your new admins. You can only add your friends or people who already like this Page. [/TR] [TR="class: _51mx"] could not be added as an admin. The email may be invalid, you may not have permission to look up this person using their email, or they may already be an admin of this Page. [/TR]Facebook Canceled the option? and if i already put an hidden manager i can take my page back?
