Thread:Extension talk:VisualEditor/cannot creat new pages because of JS error

I am using VE successfully in the last months (on MW 1.25alpha), however - after updating MW and VE, VE cannot create new pages, because of this JS error: Exception in load-callback in module ext.visualEditor.mwreference: load.php:175 TypeError: Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element'.
