remove text from footer

Hi, I had removed previously the text that says ” Supreme Directory Theme – Powered by WordPress” with code that was given to me by your team as shown below. However, for some reason, the footer text is back. My text is still there but it has been displaced.

What can be causing this and how can I remove it again?

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 ‘MY FOOTER INFORMATION’;
}
