I think it could be to do with the header.php file not linking to the stylesheet.
This is what the header.php looks like:
<!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<?php
if(user_agent_m() == ‘mobile’)
echo ‘<meta name=”viewport” content=”width=384″>’;
else if(user_agent_m() == ‘tablet’)
echo ‘<meta name=”viewport” content=”width=1024″>’;
else
echo ‘<meta name=”viewport” content=”width=1350″>’;
?>

jQuery(document).ready(function () {
jQuery(‘.categories > ul > li:last-child’).addClass(‘last’);
});
</script>
