Customise Theme link hasn’t disappeared from the toolbar, now it can be found in here: “Appearance” → “Customize” (this is the original place for the link, according to Customizer API).
You can restore the link with this code:
function customizer_admin_menu_link() {
add_menu_page( 'Customize', 'Customize Theme', 'edit_theme_options', 'customize.php', '', 'dashicons-art', 105 );
}
add_action ('admin_menu', 'customizer_admin_menu_link');
you need to add this into: wp-content\themes\revelance\inc\customizer\customizer.php file. Add the code directly below <?php .
About Custom CSC field: We need to remove this field because in the latest version of WordPress every input field within the Customizer is escaped.
For now you can have a custom css field via one of the many plugins.
Best Regards
