Error: "I experience trouble in edit mode (&action=edit) since I installed BlueSpice. Out of edit mode everything looks fine. When in edit mode of any page it looks like some CSS of the template is not loaded. Testing another template (vector) has the same behavior. There is no difference if VisualEditor is enabled or not. The VisualEditor itself looks fine and works. To make sure there is no complication with other extensions I set up a clean fresh MediaWiki installation without any extensions and then installed BlueSpice - same behavior. I tried different up to date browsers on different clients - same behavior. I checked Apache2 and PHP logs - logs are clean." Solution: "I have found a solution.We were ignoring the Suhosin-message during the installation. Setting suhosin.get.max_value_length = 2048 (php.ini) solved this issue."
