No tax on Front-End

Hi.
I have two hikashop pages running.
One like it is supposed to, the other not.

My problem is with taxes;
I have a default tax rate of 25%, which works and is applied to the back-end side of things.
On the front-end however, the price without taxes is always shown, even if I set up the configuration to show with taxes.
-If a choose to show both (with and without taxes), it shows the price without taxes twice.

As it works on my other site, I am sure I am the one to blame, but I am clueless as to why this happens.

Hope you can help.

I have no idea why, but today it works... strange
