URL Friendly

Oi tudo bem? Espero que me possam dar uma ajuda, estou implementando o URL amigavel, mas por alguma razão não funciona.

Diz "Page Not Found"

Fiz todos os passos para o fazer mas não me funciona quando ponho o URL que pretendo http://dominio.com/pox/jobs/1

Aqui vai o que tenho no htacess:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /pox/

RewriteRule ^jobs/([A-Za-z0-9-]+)/([A-Za-z0-9-]+)/?$ jobs-detail.php?jobid=$1 [NC,L]

</IfModule>

PHP Code:

require_once('../connecttodatabase.php');
mysql_select_db($database_excal, $excal);

//build query
$query_rsJobs =

 "SELECT
 * FROM jobs";

if (isset($_GET['jobid']))
 $jobId = $_GET['jobid'];
else if (isset($_POST['jobid']))
 $jobId = $_POST['jobid'];

if (isset($jobId))
$query_rsJobs .= " WHERE id_job = " . $jobId;

//execute query
$rsJobs = mysql_query($query_rsJobs, $excal) or

 die(mysql_error());
$row_rsJobs = mysql_fetch_assoc($rsJobs);
$totalRows = mysql_num_rows($rsJobs);

// build root XML element

$jobs = new SimpleXMLElement("<?xml-stylesheet type=\"text/xsl\" href=\"jobs-detail.xsl\"?><jobs></jobs>");

// loop data and build data structure
$i=0;
while ($i < $totalRows) {

 $jobId = mysql_result($rsJobs, $i, 'id_job');
 $jobTitle = htmlentities( mysql_result($rsJobs, $i, 'title'), ENT_QUOTES, 'UTF-8');
 $jobCategory = mysql_result($rsJobs, $i, 'id_jobCategory');
 $description = htmlentities( mysql_result($rsJobs, $i, 'description'), ENT_QUOTES, 'UTF-8');
 $date = mysql_result($rsJobs, $i, 'date');
 $country = mysql_result($rsJobs, $i, 'country');
 $company = mysql_result($rsJobs, $i, 'id_company');
 $city = mysql_result($rsJobs, $i, 'city');

$sql_cat = "SELECT * FROM jobs_category WHERE id_jobC = '$jobCategory'";
$con_cat = mysql_query($sql_cat);
$mostrar_cat = mysql_fetch_array($con_cat);
$jobCategory2 = $mostrar_cat['job_name'];

// Empresas

$sql_comp = "SELECT * FROM companies WHERE id_company = '$company'";
$con_comp = mysql_query($sql_comp);
$mostrar_comp = mysql_fetch_array($con_comp);
$companyName = $mostrar_comp['name'];

 $job = $jobs->addChild('job');
 $job->addChild('jobId', $jobId);
 $job->addChild('jobTitle', $jobTitle);
 $job->addChild('jobCategory', $jobCategory2);
 $job->addChild('company', $companyName);
 $job->addChild('description', $description);
 $job->addChild('date', $date);
 $job->addChild('country', $country);
 $job->addChild('city', $city);
 $job->addChild('link',
 'http://localhost/jobs.php?id=' . $jobId);

 $i++;
}
mysql_free_result($rsJobs);

//format for pretty printing

$dom = new DOMDocument('1.0', 'UTF-8');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML($jobs->asXML());

//Send to browser

header('Content-type: text/xml');
echo $dom->saveXML();
