If it is not going to the ELSE block then you need to check the query the mentioned refid and check if it's really getting a record.

How about moving away from these mysql_functions to mysqli or pdo? These functions are deprecated since PHP 5.5.0 and are completely removed in PHP 7.0.0. Otherwise, if you still need to do this, have you tried using an incrementing counter instead of using mysql_num_rows?
PHP
function submenu($parentid = 0)
{
    $sql = mysql_query("SELECT * FROM test WHERE refid=" . $parentid);
    
    echo '<ul>';
    
    $numRows = mysql_num_rows($sql);

    // I don't remember exactly, the counter should start either with a 0 or 1
    $i = 0;
    
    while($row = mysql_fetch_array($sql))
    {
        if($numRows > $i)
        {
            //echo '<li><a href="' . $row['userdefined'] . '">' . $row['name'] . '</a>';
            echo '<li>' . $row['name'];
            submenu($row['id']);
            echo '</li>';
        }
        else
        {
            echo '<li><a href="' . $row['userdefined'] . '">' . $row['name'] . '</a>';
            submenu($row['id']);
            echo '</li>';
        }
        $i++;
    }
    
    echo '</ul>';
}
