I was making on a Clipper child the, for the design purpose, i was need to remove(reorder) the header, so i was using the remove_action('appthemes_header', 'clpr_header');. After searching the documentation of apptheme I have got nothing for clipper child theme, later I figure out it’s same as classipress. And was following there 2 part child theme tutorial. There I have got another idea to overwrite the core function, tried that as well(with the function clpr_header) and that give me a blank page or two header like below
after spending few more hr on apptheme forum and documentation, i have tried my favorite thematic child theme way and bingofunction unhook_header() {
remove_action('appthemes_header', 'clpr_header');
}
add_action('init','unhook_header');
