I everyone,
I have a long time running site (J 3.8.5 / S 3.15.0). I haven't added a new app folder for some time. Now i need one and adding is not possible. If I fill out the form and save it, an empty form opens again. My app folder isn't being saved. No error alert. What I see is that in the url there is "id=0".
Doe you have any ideas?
Regards
Alex
