I have a big problem with your Publisher. New installed, in the backend no changes. Only saving Content -> issues and the frontend is no longer working. The same happens on your demo site. What to do ???
I don't have Access to publications and issues at the frontend.
For example I have the menu item http://agenbach.com/de/neues-aus-aller-welt
This is linked to Publisher "List for all publications". But it does't work at frontend. I am redirected to the Publisher Information page.
At the Moment i can't check if publications and issues are working.
