3. When adding a listing/an event, the region as well as the city have to be specified. In Germany, the city Berlin is placed in the eponymous state Berlin. I assume that this is what causes “-1” to be added in the URL for listings that have that issue.
I would appreciate if you could point me in the right directions to solve these things.
