The system avatar is missing after migrating to S3 storage. Although posts and user avatars were successfully migrated, the custom system avatar failed to update due to a URL rewrite issue.
The issue is caused by the S3_CDN_URL being appended to the forum URL, resulting in an invalid URL. For example: https://forum.tosdr.org/https://tosdr-forum.s3.eu-west-2.jbcdn.net/original/1X/3662711e5030823983d25ac319ce6b9a7ad030e6.png.
JustinBack checked the database and found that all uploads were fine, and suspects the issue might be related to this line of code.
Changing avatars does not work either, whether using Gravatar or letter images. The issue persists despite reinstalling the forum and re-migrating the site.
It doesn’t seem to update the avatars either regardless of a 200 OK
