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

[Puntocom]

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(
  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?

If using the same memcached server for both then be sure to specify a unique prefix for each forum:

Defining a Cache | XenForo

$config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_';
