Hi Rikard,

Thank you very much. Pages are editable with AVIA Layout Architekt again. All necessary changes were made meanwhile. ;-)
However one page does still not open properly: /datenschutzerklaerung/
The elements cannot be loaded by your editor: “Service unavailable”.
When switching to Standard Editor, the short code box shows up. Any saved change results in a broken html-code.

You help is very much appreciated,
Uwe
