Errors up and down the entire page

This is the error that I see:

Strict Standards: Non-static method JSite::getMenu() should not be called statically, assuming $this from incompatible context in /home/branchin/public_html/templates/gk_boutique/lib/gk.framework.php on line 602

It is going down the entire page.
