Fresh setup leads to Unauthorized

[Starstruckk]

Summary

After a fresh install of Wiki.js v2.5.307, administrative users are unable to access pages - receiving:
“Unauthorized You cannot view this page” , even though the account is correctly flagged as an administrator in the database.
Granting admin rights to the guest account restores access for all users.

Environment

Wiki.js: v2.5.307
Database: PostgreSQL v14.18
Node.js: v20.19.0
Operating System: Unraid v7.1.4

Steps to Reproduce

Clone the Wiki.js repo or install on Unraid either the linuxserver's wikijs or Selfhosters's wikijs docker containers

Install dependencies and run the setup wizard.

On the setup page, enter a new administrator account (e.g. admin@example.com, password ••••••).

Complete setup and log in with that admin account.

Observe the “Welcome to your Wiki” landing page.

Click Create Home Page or the Administration link.

Actual Behavior

Clicking on Create Home Page or the Administration page leads to:

 Unauthorized
  You cannot view this page

In the userGroups table, the newly created user has groupId = 1 (administrator group)

Workaround:

Assigning admin privileges to the guest user restores functionality for all accounts...

UPDATE userGroups SET groupId = 1 WHERE userid = 2;  -- guest user is userId = 2

allows the original admin account to access all pages.

Expected Behavior

The newly created admin user should have full access to all wiki and admin pages without needing guest-account elevation.

Logs & Screenshots

No warnings or errors in the logs during the initial setup nor before/after changing guest user's privileges.

Directly after I create my credentials during the setup page and then trying to access homepage / administration page:

users table where I can see that my email has been created, with name Administrator:

userGroups table where I can see that my userId (1) has been granted the Administrator privilege:

changing guest userId (2) to groupId 1 (from guests permissions to admin)

grants me access to the wikijs UI:
