Jack Chappell on "Website not loading"

I accidentally changed some text in class-footer-footer_main.php on my Customizr theme, it reads:
sprintf( '<p> &middot; &copy; %1$s <a href="%2$s" title="%3$s" rel="bookmark">%3$s</a> &middot; Designed by %4$s &middot;</p>',
I'm not 100% sure as to what it said before this but is there anything obvious that is causing my site to just not load?

Thanks
