Menu does not appear in the mobile version

Hello everyone, I'm trying to include a page that has an external menu, requested in PHP with require, but I still tried the include, but it still has the same problem, as the screenshot below the menu only appears in the desktop version, in the chrome mobile version does not appear, does anyone have any idea what it can be?

As I said above, it is a normal page in PHP, both the print page and the menu.php, and none of the pages that the menu requires, the mobile version does not appear;

Code

<?phprequire'head.php';require'conn/conexao.php';date_default_timezone_set('America/Sao_Paulo');?><styletype="text/css">
