Page Manager - Create and manage additional pages!

[vids]

After installing and activating it, i get this message when i try to access the Page Manager

Access Denied

You do not have permission to access this part of the administration control panel.

I am logged in admin account .

Edit :

Thats weird,
I can acccess via the first admin account i had created while installing mybb but can't via the other admin made later.

Just check into it.
