HiI have created a new category Klær2 (and a spare test) and i am trying to let category Klær2 be parent ofGenser but I am not able to choose that category. What could be wrong?

Hi,

I've tried on my end and it works fine:
take.ms/0T5JR
So it's not a problem of special characters.
Try to click on the "rebuild" button of the categories listing and the "check database" button of the HikaShop configuration. Maybe that will help.
