Supreme Directory Footer Copyright Text

Hello,

I had previously been able to change the footer copyright text in the Supreme Directory using the following code but it seems after a recent update that no longer works. I tried deleting and re-installing the code but that didn’t work either. Is there anything that is missing or needs added?

Thanks,
Andrew

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 Text’;}
