[Ser.]

Hi.

I'm quite new with Prestashop. I installed blck.zip theme, that is an improved version of the classic theme.

When clicking on a product, get this:

I know it's Faceted Search that cause that, and it's proven because the error disappear when I uninstall this module.

- Also I have a problem with the favicon (format .ico, and created with the Prestashop favicon tool on the addons.prestashop site).

It worked with both my back and frontoffice, and now it is shown only on the bo.
