after I edit my config.php for allowed staff I use this :

<?php

 //clear cache
$memcache = new Memcache;
    $memcache->connect("localhost",11211);
    $memcache->flush();
    //print_r($memcache->getStats());
header("Location: {$INSTALLER09['baseurl']}/index.php");
?>

saved as memcache.php & then upload to /var/www then run it like so : http://domain.com/memcache.php

I had the same issue but that seems to fix my problem good luck!
