Fatal error: Redefinition of parameter $post_id in C:\xampp\htdocs\wp-content\themes\couponer\functions.php on line 2533

function coupon_smeta_images( $meta_key, $post_id, $default, $post_id){
    if(class_exists('SM_Frontend')){
        global $sm;
        return $result = $sm->sm_get_meta($meta_key, $post_id);
    }
    else{       
        return $default;
    }

/* check if smeta plugin is installed */

Answer 1

You have a duplicate $post_id parameters in your functions. Try remove one like this:

function coupon_smeta_images( $meta_key, $post_id, $default){
    if(class_exists('SM_Frontend')){
        global $sm;
        return $result = $sm->sm_get_meta($meta_key, $post_id);
    }
    else{       
        return $default;
    }
}
