Error: I got the last package Bluespice 2.23.2 + Mediawiki 1.23.11. it seems that the sepcial link ImageMApEdit is not available under an image file
Solution: Please check your <mediawiki>/extensions/BlueSpiceDistribution/BlueSpiceDistribution.php You may want to compare it to the current BlueSpiceDistribution.php.template file. Maybe the extension is just not activated (You can also look at "Special:Version" to check this).
