The Meta Discourse small logo image is broken in default light themes, including Default, Material Design, and Graceful, but only on desktop. Alteras reported the issue, providing screenshots and a code snippet, and outlined steps for reproduction. The problem seems to be related to an “Access Denied” message when accessing the logo image URL directly. hello-smile6 was unable to reproduce the issue using Chromium, but could reproduce it using curl. NateDhaliwal also experienced the issue while logged out and using Meta Branded Light mode.
