"Add to cart" button not working

[broc93]

Hello! Suddenly the "add to cart" button on my webiste isn't working anymore! I haven't made any big change to the website in the last days, only some edits to the content, as far as I remember, but the button stopped working.
I don't know anything of Javascript, so I'm wondering if someone could help me. It would be really appreciated
Here's my website: www.dietabenesserehl.it

Thank you in advance,
Luca

Yes, you do have a JavaScript problem:
TypeError: $.facebox is undefined
$.facebox.settings.closeImage = closeImage;

Since VM now uses Fancybox rather than Facebox, first tell us which exactly versions you are using:  http://forum.virtuemart.net/index.php?topic=79799.0

Oh, I'm sorry, I thought it could be seen from the website. Anyway, it's 2.0.10
Thank you in advance,

Old versions. Could you update?

[broc93]

Well, last time I updated everything didn't work anymore (I mean, the graphics were all messed up, as far as I remember), so I reverted back to this version...

VM2.0.10 was released a year ago, so few people in this forum will have it in use any more - that makes it difficult to guess what your problem is.

Things don't stop working suddenly unless you or your host makes some changes that cause this to happen. Impossible to diagnose without knowing exactly what you (or your host) did.

Well, I don't really know when the button stopped working
Anyway, what could I do to solve the problem? (except using a backupped version of the website)

Try the backup on a subdirectory of the same server - that will allow you to rule out the problem being host related.

Compare current and backupped versions of your website (Kdiff program).
