In a vanilla MediaWiki, I would edit the LocalSettings.php
to change the line:
## The relative URL path to the logo. Make sure you change this from the default,
## or else you'll overwrite your logo when you upgrade!
$wgLogo = "$wgScriptPath/resources/assets/wiki.png";
However, this has no effect with BlueSpice and that wiki.png is not being used. How can I change the logo in BlueSpice?
