what is the correct way to add repositoriy targets for my private OBS installation

I followed this article] to set up my own OBS instance. Although I did see a “Meego 1.2.0” option in my distribution selection page after setup, but when I click it, an error shows up saying “Can not add repository: Path elements is invalid and Path Element: Link can’t be blank”, which sounds confusing already, and I don’t know what when wrong consider I did exactly what the article mentioned.

Does anyone know what am I missing here?
Thanks~
