Deleting Footer

So I wanted to delete the footer on my geodirectory. I found a way someone from here helped me out.

I added the snippet:

function dt_remove_default_footer() {
remove_action( ‘dt_footer_copyright’, ‘dt_footer_copyright_default’, 10 );
add_action( ‘dt_footer_copyright’, ‘custom_dt_footer_copyright_text’, 10 );
}
add_action(‘init’, ‘dt_remove_default_footer’);

function custom_dt_footer_copyright_text(){
echo ‘ New Footer © 2017 ‘;
}

… issue is that now is showing again. 🙁

please help?
