Hello,
thanks for your feedback.
I did not know about the bulk export. Interessting.
I was opening the side from the Quickstart pack on my private server. It works fine. The layout of the page "home" from the template wayne crop was interesting > open the side (frontend Editor) > three dots > export with download (with and without seo)
Opening my site (all updates) > new page > import the jsonfile > it works (as many times before) >> But it works not with the frontend editor ONLY with the backend editor.
Thanks,
Alex
