Server Error on SideBar

Issue Summary

This issue is concerning wagtail’s sidebar, when a user has been created within the CMS, the Root Page/Pages on the sidebar don’t load and the following error appears: status_code : 403 Endpoint : ...cms/api/v2beta/pages/?child_of=1&for_explorer=1

Response :

Although it works perfectly when the user has been created from the terminal as superuser which makes me think it might be related to permissions. So I tried with many different users and permissions and allowing access to the Root page too and making him an Admin, but the issue remains. The permission side of thingns still works perfectly and can be accessed by the dashboard :

Steps to Reproduce

After setting up a wagtail project with some lists and detail pages with “HomePage” as Root Parent. Structure : (Root)HomePage > (List Page) News > (Detail Page) Articles

1. Create a new Permissions Group.
2. Give Group Page Permission to the Root Page & News (Tried all kind of combinations).
3. Create a new user under Settings > Users > Add a User.
4. When creating the user, adding it to the correspondent group.
5. Login as the newly created user.
6. Open sidebar and the error should appear.

Technical details

• Python version: Run 2.7.10
• Django version: 1.11.13
• Wagtail version: 2.1.11
• Browser version: Tried with Firefox 61 & Chrome 67.

@LuisJLopez I had the same issue adding wagtail to an existing project. In my case this issue was related to my rest-framework project configuration. If you overrode some of the following settings (children of REST_FRAMEWORK dictionary):

• DEFAULT_AUTHENTICATION_CLASSES
• DEFAULT_PERMISSION_CLASSES

be sure that wagtail can use the rest_framework.authentication.SessionAuthentication

@gasman from a fresh install there is no issue, so it must be related to the way we have setup the structure within the project, thank you for your help 😃
