Manual talk:Interface/Sidebar/Hacks

Hi, I have a new version of Mediawiki (1.25) and checked Monobook.php and Vector.php but couldn't find end of the left (by default at least) column  to add a banner to the sidebar (PHP) :(
 * I'll update the page for MediaWiki 1.27. --87.123.63.88 14:01, 22 August 2016 (UTC)
