After upgrading from 1.26 to 1.27 my Wiki does not work anymore. Die Content is visible for a second and then it disappears. There are no php errors shown. In Chrome Developer Tools I see the javascript arrors on the picture attached..
The same happens if i import the database from this site in an new clean Wiki.
