Hi Locutus,

thank you very much for your response.

Hmm..to be honest I don't want to turn on the SEF Feature in Joomla...

Is there an other way to get the missing variable on the "error page" 



I need the topic id in the url to start a small feature on the error page...

Best regards,

Cuba

Sorry for the tripple post - I think I've found the part in the smf.class.php in the component directory that cuts the topic id...

function integrateExit($param)
{
    global $context, $txt;
    global $jsmfConfig;
    $jsmf =& jsmfFrontend::singleton();
    if (isset($context['login_error'])) {
        if (strcasecmp($context['login_error'], $txt[40]) == 0 ||
            strpos($context['login_error'], 'action=activate;sa=resend;') !== false) {
            $jsmf->doLogin(false);
        }
    }

    if (defined('_VALID_MOS') && isset($context['sub_template']) &&
               (strcasecmp($context['sub_template'], "kick_guest") == 0 ||
                strcasecmp($context['sub_template'], "fatal_error") == 0)) {
        $_SESSION['MH_WARNING'] = ob_get_contents();
        ob_end_clean();
        header('Location: '.str_replace(array('&'), array('&'), $jsmf->fixLink()));
        exit();
    } else {
        return;
    }
}

  Please help me
