The discussion addresses a bug where the user card fails to display properly when clicking on an avatar of a deactivated account, particularly in topics with oneboxes. pfaffman first noted the issue, linking to a topic where the user card either doesn’t appear or disappears immediately. codinghorror identified a JavaScript error in the console as the cause. sam confirmed the issue occurs when accessing a deactivated account, suggesting the system should handle 404 responses by displaying a message like “account not active.” pfaffman acknowledged the issue, and sam clarified that the bug is already assigned, with nbianca having fixed it in a pull request here.
