XF 1.4 Blank page when I enable memcached in one forum (another forum in the same server works fine)


Well-known member
Hello. I run a VPS with two XenForo installations. Memcached is working fine in one forum but, when I enable it in the other forum (same server) I get a blank page.
$config['cache']['enabled'] = true;
$config['cache']['cacheSessions'] = true;
$config['cache']['backend'] = 'Memcached';
$config['cache']['backendOptions'] = array(
  'compression' => false,
  'servers' => array(
  // your memcached server IP /address
  'host' => 'localhost',
  // memcached port
  'port' => 11211,
  • XenForo 1.4.5
  • PHP 5.5.26
  • Nginx 1.7.10
  • Memcached 1.4.21p1
  • pecl-memcache-3.0.6p5

Can you help me, please?
