How do I clear/flush user avatar cache in commit history page?

After I update gravatar_ssl_url and gravatar_plain_url options, the comitter’s avatar displayed on project home page and commit detail page is correctly, but the avatar in commit history list was the old cache, how can I flush the cache in history list?



I’ve tried commands below, none works:

gitlab-ctl reconfigure
gitlab-ctl restart
gitlab-rake cache:clear
gitlab-rake tmp:cache:clear
gitlab-rake assets:clean
