The links are not working

Hello,

I have a huge problem of my website and I have no idea of where it can come from : I manage to add a document to my cart but none of the links on the checkout page are working : I can't "buy other documents" or validate a coupon, I can't "Complete Order", I can't remove an item from the cart. It's just as if Javascript wasn't active on my computer but I checked and it is active. I tried on Firefox, Opera & Internet Explorer and I don't find any solution.

Is there something I might have forgotten to activate ?

Thank you in advance for your answer !

Solution found ! It comes from the foreign language file I created. It seems the component doesn't like the apostrophes.
