Hi Christian
Thank you very much for your reply. I have tryed to contact Cecilia several times but got no answer…
So I took the whole Website to my development server and deactivated all other plugins. The problem was still there.
Something must be wrong with the Home page. All other pages are working perfectly.
If I make a change on the german Home page and save, it overwrites the italian version of the Home page. The italian menu and the italian Blog widget are still there in the correct language but all other content has changed to german. Even the italian Version of Slider Revolution Slide-Show has changed to the german one.
To change this to the italian Slide-Show, I have to edit the italian Home page in Wordpress (not in Cornersone) to set the italian Slider below Masthead. When saving, thefollowing message appears:
On tuccillo.ch the following is displayed: You are updating a double entry. In order not to lose its change, WPML will post this contribution so that it will be independently translated.
(see attachment).
Could this be a Note about the problem?
Thank you very much for your help!
