Hi, I read all the possible topics but still I'm stuck with the following.

I created a website and want to grand my customer access to edit and approve pages, so I created a USER and set the following permissions :

- View
- Preview Page As User
- Edit Properties
- Edit Contents
- Change Page Type
- Approve changes

And I added the user to Block and Stack permissions in the Dashboard.

When I log into the site using his account I can do everything I want him to do. When I click on a block and click Manage Stack Contents I get an error (forbidden) page on this link:
/index.php/dashboard/blocks/stacks/-/view_details/138

I tried setting permissions indicidually on the main Dashboard page and the Stack page using the Show Systems Pages in the Site map. However I cant figure out what I'm missing or doing wrong.

Hope someone can help, thanks !
