Hello, thank you for helping me. That settled, the filters are now appearing.

    I made a test purchase, this now appearing only this error:

    ERR (3): Notice: Undefined variable: class in /chroot/home/onezero2/1000lens.com/html/app/design/frontend/sns_avaz/default/template/catalog/product/list.phtml on line 211

    It appears repeatedly.

    How can I solve this problem?

    Once again, thank you and await your response.
