Test Permissions and Analyze Permissions Does Not Work with Wiki Permissions
Xenforo, to help with permissions troubleshooting, has two tools: Test Permissions and Analyze Permissions. When I was trying to figure out why a user could not edit the wiki, I tried using Test Permissions to view the board with their permission set, but this did not take wiki permissions into account. Even when I had an article set to collaboration prevention with my own account, when testing another user's permissions I could still edit that article.
Analyze Permissions also does not display VaultWiki permissions.
