Virtuemart & myStore

Hello,
I have a problem with my e-commerce site:

1 - Changes to the size of the template are not saved, if I put as my default 980px always opens with the template as the default size of installation.

2 - When I click on add a product sheet, I do not open the lightbox, and then the cart is not updated. To see the truck I need to update the current page.

3 - The photos I did not open in the lightbox when I click on the picture of a product I opened the link to the image.

When I open the site with IE in the status bar of the browser I find that an error is as follows:


Dettagli errore pagina Web

I think it's a problem or ajax mootools.

What to do?

Thanks
