Thread:Project:Support desk/Where is the watchlist maximum days site variable configured?/reply

I've found Manual talk:$wgRCMaxAge - but as others have already commented in the discussion, after setting that value to 91 days in LocalSettings.php, and then running maintenance/rebuildrecentchanges.php (which confirms 91 days), the watchlist option for the user is still limited to 7 days. Is there a second variable lurking here?
