Cleaning Permalink

Hi!

Please add this in the functions.php file:

add_filter('avf_portfolio_cpt_args', 'avf_portfolio_cpt_args_mod');
function avf_portfolio_cpt_args_mod($args) {
	$args['rewrite']['slug'] = 'portfolio';
    //$args['rewrite']['with_front'] = false;
	return $args;
}

add_filter( 'post_type_link', 'ava_remove_custom_slug', 10, 3 );
function ava_remove_custom_slug( $post_link, $post, $leavename ) {
    if ( 'portfolio' != $post->post_type || 'publish' != $post->post_status ) {
        return $post_link;
    }

    $post_link = str_replace( '/' . $post->post_type . '/', '/', $post_link );

    return $post_link;
}

After that, go to the Settings > Permalinks panel then click “Save” to update the permalinks.

Regards,
Ismael
