Uninstall

At some point, I tried to install the module following the instructions. I failed.

How I am trying to disable it and remove it, but can't.

I removed the module, and the site goes white page of death. errors_log reports:

[Tue Jul 27 02:29:58 2010] [error] [client 66.249.65.87] PHP Fatal error: require_once() [function.require]: Failed opening required './sites/all/modules/memcache/memcache.inc' (include_path='.:') in /var/www/vhosts/filiera.fr/httpdocs/includes/bootstrap.inc on line 1111

So I bring it back. I then go and remove the following lines from settings.php:

$conf = array(
'cache_inc' => './sites/all/modules/memcache/memcache.inc',
// Important to define a default cluster in both the servers
// and in the bins. This links them together.
'memcache_servers' => array('127.0.0.1:11211' => 'default'),
'memcache_bins' => array('cache' => 'default'),
);

In which case the server again goes white page of death. error_log reports:

[Tue Jul 27 02:33:10 2010] [error] [client 207.46.204.194] PHP Notice: unserialize() [function.unserialize]: Error at offset 0 of 4 bytes in /var/www/vhosts/filiera.fr/httpdocs/includes/bootstrap.inc on line 551

This line is inside this function:

function variable_init($conf = array()) {
  // NOTE: caching the variables improves performance by 20% when serving cached pages.
  if ($cached = cache_get('variables', 'cache')) {
    $variables = $cached->data;
  }
  else {
    $result = db_query('SELECT * FROM {variable}');
    while ($variable = db_fetch_object($result)) {
      $variables[$variable->name] = unserialize($variable->value); /// <<< This is line 551
    }
    cache_set('variables', $variables);
  }

  foreach ($conf as $name => $value) {
    $variables[$name] = $value;
  }

  return $variables;
}

Please advise. It's late and my site is dead.

Thanks.
