Thread:Project:Support desk/Mediwiki & Bluespice

MediaWiki: 1.25.1 PHP: 5.5.9-1ubuntu4.9 (apache2handler) MySQL: 5.5.43-0ubuntu0.14.04.1 BlueSpice for MediaWiki: 2.23.1

I have installed Bluespice for MediaWiki. When I now want to edit a page it only shows a white blank page.

Does anyone know how to fix this issue?
