It seems that smarty trigger error is deprecated

Try this :

//function Legacy_function_stylesheet($params, &$smarty)
function Legacy_function_stylesheet($params, $smarty)
{
    if (!isset($params['file'])) {
        //$smarty->trigger_error('stylesheet: missing file parameter.');
        trigger_error('stylesheet: missing file parameter.');
        return;
    }
    
    $file = $params['file'];
    
    if (false !== strstr($file, '..')) {
        //$smarty->trigger_error('stylesheet: missing file parameter.');
        trigger_error('stylesheet: missing file parameter.');
        return;
    }
