After a Pickware update, existing roles may be missing permissions because updates with new features bring new privileges. Users with admin rights are not affected.
Identify missing privileges
If a role is missing a privilege, the user receives an error message when opening the affected area, for example when opening the orders. The message usually names the missing privileges. This tells you what you need to add to the role.
Add privileges to the role
In the Shopware Admin, open Settings → System → Users & Permissions.
Open the role of the affected user.
Under Detailed privileges, add the privileges listed in the error message.
Save the role.
A user can have multiple roles, and roles can be duplicated. You can find more about roles and permissions in How do I manage different user roles for Pickware WMS?.
"Access denied" right after login
If you see "Access denied" right after logging in, the role is missing the permission for the start page. The other areas still work. Add the permission for the start page to the role to make the message disappear.
