// shortcode to list active plugins 
add_shortcode( 'activeplugins', function(){
	
	$active_plugins = get_option( 'active_plugins' );
	$plugins = "";
	if( count( $active_plugins ) > 0 ){
		$plugins = "<ul>";

$request_uri = parse_url( $_SERVER['REQUEST_URI'], PHP_URL_PATH );

$is_admin = strpos( $request_uri, '/wp-admin/' );

if( false === $is_admin ){

	// filter active plugins
	add_filter( 'option_active_plugins', function( $plugins ){

		global $request_uri;

		$is_contact_page = strpos( $request_uri, '/contact/' );

		// change elements according to your needs
		$myplugins = array( 
			"contact-form-7/wp-contact-form-7.php", 
			"code-snippets/code-snippets.php",
			"query-monitor/query-monitor.php",
			"autoptimize/autoptimize.php" 
		);

		if( false === $is_contact_page ){
