{{NUMBEROFACTIVEUSERS}} is currently only updated by updateSpecialPages.php. Thus for people with $wgMiserMode = false who never run updateSpecialPages.php, the variable will be out of date.
The magic word {{NUMBEROFACTIVEUSERS}} remains stuck at 0.
This can be seen in Special:Statistics, Special:CreateAccount and wherever the magic word is included in a page.
The Special:ActiveUsers page, however, works fine and lists the active users.
Have already tried:
initSiteStats.php --update
but it didn't help.
