問題

Scenario1

User avatar is broken in page restriction dialog and "atl" HTML attribute is shown instead. The following screenshot was taken when I tried to search a user (e.g. "test") in the dialog.

Scenario2

User avatar is broken when mentioning user. The following screenshot was taken when I tried to mention a user (e.g. "test") in a page.

診断

• Is the affected user managed in any external user management system? (e.g. Jira User Server, LDAP)
• Did you currently update the Confluence base URL? (e.g. http://example.com/confluence → http://example.com)
• Let's open developer tool on your browser to see which URL Confluence is trying to download the avatar file from
  
  • You must see that the avatar URL still refers to the old context path (e.g. /confluence/images/icons/profilepics/default.png)
• There are several similar problems but this is not the case
  1. Broken avatars/icons in Confluence after an upgrade due to corrupted cache
     • Flushing the caches didn't solve the problem
  2. After Adding a Context Path to the Base URL, Icons Appear as Broken Images
     • Confirmed server.xml and confluence.cfg.xml had been updated correctly

原因

Confluence has the user avatar URL information in Lucene indexes as well and just changing the base URL doesn't update it due to CONFSERVER-54158 - Getting issue details... STATUS .

ソリューション

Rebuilding the search index solves this problem.
