I am looking for a plugin which can allow a user only to see and edit one single page in the backend. Means: user 1 can edit and see page #20 user 2 can edit and see page #21 ....
The other pages, posts, settings can not be entered, seen or edited by these users.
In the frontend everyone of these users has one page. It is for a customer who has 20 customers who should have their own personal page.
