Running BlueSpice/ MW 1.27(I know it's old).
Wanting to set the sie bar (showing Links to Main Page/ Recent Changes/ Random Pages/ Tools,..) to not floating. What file do I have to edit? Tried several but can't find the right file under skins>BlueSpiceSkin>resources
BlueSpice related questions may probably better be asked at https://sourceforge.net/projects/bluespice/support
The file you are looking for is most likely `resources/screen.layout.less` [1]. Check the styles for the `#bs-nav-sections` selector.
Modifying source code is in general not a good idea. As there won't be any updates for your software version there is at least no risk of overwriting you changes on an update though. Yet, it is highly recommended to use a more recent version.
