Maybe something gone wrong through import from Box. Delete current portal and add manually. Please tell us if it worked.Thx.
Update according this issue:
I tried to delete 2 portals and then add them again manually.
Now i can edit the portals without problems,so it seems that something happens when you import portals from the the box.For knowledge: I use Formuler Z12 Ultra and mytvOnline4.
