Dear Moritz,
Could you, please, direct me in a little bit of detail to the WooCommerce option of hiding the prices and the AddtoCart button to non-registered members?
You mentioned it in your first message: "WordPress' buildt in PW-protection does not do this. there is a nice extension (catalog visibility options)" Probably, I am not looking in the right direction:) But that's exactly what I need - to hide the prices only and show them to registered users.
Thank you and waiting to hear:)
