When a Viewport is accessed by anonymous users, the following error message displays, while logged in users can view the Viewport without an issue.


In most cases, this is a result of inconsistent permission configuration that happens if Scroll Versions' version integration is active. It is caused by granting anonymous users access to the space in the Space permissions, while also not configuring any space version to be shown in Viewport. Thus, anonymous users have access to the space, but no content that they are permitted to see. 

  1. Navigate to Scroll Add-ons > Versions
  2. Click on ••• on a version you would like to show in Viewport.
  3. Select Show in Scroll Viewport.
