I'm not sure how this happened but all the prices in the shop are messed up. :/
1. The prices shown to the customers are too low (-25%)
2. The prices shown in the product listing (admin page) are too low (-25%)
3. The price when editing a product shows the correct amount.
4. In the cart the prices are correct.
How is this possible and what can I do to solve this?
Any help or suggestions are highly appreciated!
