Prices Displayed Changed

Hi guys,

I have a problem in my website: http://projectpieta.com/product-category/men/
Take a look at the prices. They are not the prices I have in my backup.
Prices displayed are higher than the one I wrote. But when you add the product on the bag at the next step in the cart the price is ok.
For exemple:
– This t-shirt is displayed 87,50€ > http://projectpieta.com/shop/men/organic-raw-shirt/
– Add it to the bag
– Then at the cart it’s the real price: 35,00€
Do you have any ideas where does the problem come from? It’s very problematic because we need this ok in order to earn our money, it’s an association we live with the website!
I though it was currency switcher, and WPML, so i deactivated them but it’s still the same problem you see.
Please help us!!

Best regards!!
