Sometimes information in the StateBar isn´t necessary or even not wanted, for example at the main page or portal pages. Here you can hide the statebar by using this behaviour switch __NOSTATEBAR__. Enter the edit mode and change to the wikicode mode. Now insert __NOSTATEBAR__ at the end or at the beginning of the page and save this change. The StateBar won´t be shown at this article anymore.
The StateBar shouldn´t be shown in any article of the wiki? Don´t worry, you don´t have the set the behavior switch in every single article. You can also deactivate the StateBar globally. But: You need to have administrator rights for this, because it is a setting in the admin preferences. Switch to the admin tab in the main navigation and then go to
Preferences -> BlueSpice -> BlueSpice-MediaWiki settings -> Status bar
and uncheck the box “Display Statebar”. The StatBar is deactivated in the whole wiki now!
