In JNews, WPBakery in posts is turned off by default. To turn it on, add the code below to the theme’s child theme functions.php.
add_filter( 'vc_check_post_type_validation' , 'jnews_vc_post_type', 99, 2 );
function jnews_vc_post_type( $value, $type ) {
if ( $type === 'page' || $type === 'post' ) {
return true;
} else {
return false;
}
}
