Hi Jon,
Thanks for your reply. You shouldn’t remove it using the custom CSS code. To change the copyright, use the following code. Insert into the Code Snippets plugin https://wordpress.org/plugins/code-snippets/ .
add_action('after_setup_theme', '_my_sd_footer_changes',15);
function _my_sd_footer_changes(){
remove_action( 'dt_footer_copyright', 'dt_footer_copyright_default', 10 );
remove_action( 'dt_footer_copyright', 'sd_footer_copyright_default', 10 );
add_action( 'dt_footer_copyright', 'custom_dt_footer_copyright_text', 10 );
}
function custom_dt_footer_copyright_text(){
echo '© 2018 Supreme Theme LLC. All Rights Reserved.';
}
use this custom CSS code below into WP > Appearance > Customize > Additional CSS.
.dt-nav-toggle.dt-mobile-nav-button-wrap {display:none;}
