Hy i have the same problem on an old installation; no buttos for upload,..

        $tableColumns['dateiname'] = array(
            'display_text' => 'datei',
            'maxlen'   => 100,
            'perms' => 'EVCTAXQSHOF',
            'file_upload' => array(
                'upload_fun' => array(&$this, 'handleUpload'), 
                'delete_fun' => array(&$this, 'handleDeleteFile')),
            'table_fun' => array(&$this, 'formatLinkDownload'), 
            'view_fun' => array(&$this, 'formatLinkDownload')
);

function formatLinkDownload($col,$val,$row,$instanceName,$rowNum)
    {
        $html = '';
        if (!empty($val))
        {
            $html = '<a target="_blank" href="'.htmlspecialchars($val).'">test</a>';
        }
        return $html;
    }

                'delete_fun' => array(&$this, 'handleDeleteFile')),
