I tried it but it did not worked

also i checked in parent theme functions.php . There function name is catchbox_footer_content() instead of mh_catchbox_footer_content()

i did as u said but i did not work . I just want Copyright part to be diplayed. It removes the footer section but it doesn’t show anything means second part of code you send.
