After updating phabricator today, images in comments are not rendered anymore. Clicking them for fullscreen view still works.
Server has no hostname, only IP address, if that is of any concern.
Running on lighttpd, this is what the logs say:
2014-08-19 12:13:32: (mod_fastcgi.c.2695) FastCGI-stderr: [Rendering Exception/Exception] Refusing to redirect to local resource "http://192.168.0.175/file/data/gjyojaltobp2vbhvikio/PHID-FILE-fvtv2hrcb4xcsfsqji3i/preview-SAM_3693.JPG". The URI has a domain, but the redirect is not marked external. Mark redirects as external to allow redirection off the local domain.
