* edited for security reasons (it was my domain name in the log edited here)

it tells me this:
DEBUG - 29-07-2010 20:45:42 --> Global POST and COOKIE data sanitized
i cant seem to know what 'sanitized' means (google tells me in dutch its cleaned) and my

Code:

$config['global_xss_filtering'] = FALSE;

i cant get any post or get variables using:

Code:

$config['enable_query_strings'] = FALSE;
$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-'; (maybe ? is needed?)

using this form:

Code:

<form method="get" action="zoek/">
                        <fieldset>
                            <legend>Uw plaats, postcode of regio</legend>
                            &lt;input type="text" id="key" value="" class="side" /&gt;
                            &lt;input type="submit" value="Doorgaan" class="side" /&gt;
                        </fieldset>
                    &lt;/form&gt;

and this code to get the parameters:

Code:

$keyword = $this->input->post('key');

if(!$keyword){
    $keyword = 'geen zoekopdracht gevonden.';
}

? i have read all above, none still working not even the CI 2 Get Parameters patch.
