Control panel dissapears


In the last versions of OpenHab2 (extract from git), since two weeks I think, the control panel doen’t appear. There are some groups configured. I’ve added some things and items but the control panel stay hidden.

The issue appears also with demos without modification.

What is the best way to investigate this issue ?

Best regards,


That’s no issue, see for more Information.

OK. I see.
But, what kind of UI can I use then ? Basic UI or Classic UI ?


OK, I can work also with control like I did before by mention the right URI.
