Now I have a new problem:
I don’t see my pages anymore to change them. It’s okay on the web, but to change teh content I don’t see what I have made ????

Thanks, I foud it, but in My Enfold (Dutch) it is at a different place.
There is a button IMPORT/EXPORT (second from bottom, and there I found the Iconensets-Manager
So I can now do what in the vedeo was shown.
