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

Your current zone is stored in the user session. Your session must have expired since yesterday and the zone was reloaded, allowing you to see the tax where before the zone you had was outside the tax rule zone.
