症状

1. Admins are unable to access any restricted pages as administrator.
2. The checkboxes for Personal Space ,  Create Space(s) ,  Confluence Administrator ,  System Administrator  are greyed out and cannot be clicked.

再現手順

1. Ensure there is more than one group with System Administrator permissions
   1. Go to  > User Management > Groups
   2. Create a new group confluence-system-administrators
   3. Click Add Members and add yourself
   4. [グローバル権限] に移動します
   5. [権限の編集] をクリックします。
   6. Enter confluence-system-administrators to _Grant browse permission to_ and click Add
2. Check all checkboxes Personal Space, Create Space(s), Confluence Administrator, System Administrator
3. Click Save All at the bottom
4. Go to  > User Management > Groups
5. Click Delete next to confluence-administrators
6. Click Confirm

原因

The check boxes are not changeable because  confluence-administrators  is a super-super user group and it has been deleted. Thus, the group should not be deletable.  This is a bug in Confluence:  CONFSERVER-53448 - Getting issue details... STATUS .

It may be that an administrator deleted and re-added this group under a different name, such as administrators, granting them all the system administrator privileges.  However, this group will never actually have all the rights as the confluence-administrators group and it must have this exact name.

ソリューション

Add back the confluence-administrators group, with all Global Permissions.

1. Create a new group called confluence-administrators
2. Add all Global Permissions to this group
3. Add yourself to this group
4. Attempt to view the restricted pages or spaces
5. If it still doesn't work, go back to Admin > View Default Space Permissions and click on Recover Permissions
6. Browse to the space or page again
