kelex on "[Theme: Customizr] editing the footer credit and web link"

I created a child theme with css and functions.php files.I copied the scr ipt to functions.php and the lines of code shows on the page header instead of showing the edited words at the footer area of the web page.

I deleted the child theme and recreated another one and add the script to functions.php and previewed the web page and both the admin page and the web page crashed showing chinese-like inscriptions on.
