Price not changing – caused by product import – solved

I had the problem that the prices wouldn′t change anymore for user roles, but I managed to resolve it myself and just wanted to share what caused it. We had recently imported new prices via a csv file and product import. The cell format of the cells containing prices in the csv file needed to be “number” otherwise the prices would show correct in the backend, but it would not work for user roles on the website. Hope this helps someone else.
