{{REVISIONUSER}} doesn't seem to work on the Wikimedia cluster. It doesn't show anything at all. For an example, see
https://www.mediawiki.org/wiki/User:Amire80/REVISIONUSER
It does work in the latest MediaWiki master, so maybe it's already fixed, but I'm reporting just in case.
Just purge the page and you will see your user name.
Maybe a (replication?) issue on page creation.
Waaat.
Weird stuff.
It was used on @IKhitron's user talk page (through a template) and it was saved several times, and the name didn't show up. Now after purging it does.
Is there some job that purges everything? This may render a lot of pages weird until somebody bothers to purge.
Confirmed that when creating a new page on mediawiki.org, the resulting page view after it shows all text but nothing from {{REVISIONUSER}}. Not until a manual purge.
Easy vagrant repo (change localsettings.php):
# Simulate master/slave setup a bit $wgDBservers = array( array( 'host' => $wgDBserver, 'dbname' => $wgDBname, 'user' => $wgDBuser, 'password' => $wgDBpassword, 'type' => $wgDBtype, 'flags' => DBO_DEFAULT, 'load' => 0, ), array( 'host' => $wgDBserver, 'dbname' => $wgDBname, 'user' => $wgDBuser, 'password' => $wgDBpassword, 'type' => $wgDBtype, 'flags' => DBO_DEFAULT, 'load' => 1, 'fakeSlaveLag' => 0 ), );
