title: Can't configure APC for PHP
body: <p>I am having a very weird issue with my fresh dedicated server.
  It has Plesk 11 installed and I am trying to install APC in it. Everything went fine and I can see the APC configuration on the <code>phpinfo()</code>, but I am not able to configure it! I am trying with every way possible but the config shown in the phpinfo doesn't change. It doesn't show that the <code>apc.ini</code> config file is loaded in the additional ini files, but if I comment the <code>extension=apc.so</code> line inside the file, the APC goes down.</p>
  
  <p>Here comes my apc.ini file:</p>
  
  <pre><code>[APC]
  extension=apc.so
  
  apc.enabled = 1    # Turn APC cache on
  apc.optimization  = 0    # Experimental keep off
  apc.shm_segments = 1    # Shared memory segments
  apc.shm_size = 256M  # Max shared memory dependent on OS
  apc.ttl = 7200
  apc.user_ttl  = 7200
  apc.num_files_hint = 1024
  apc.mmap_file_mask = /tmp/apc.XXXXXX
  apc.enable_cli = 1 # Allow command line php to function
  apc.cache_by_default  = 1 # Enabled, 0 for filters
  apc.max_file_size = 10M # Maximum cached file size
  apc.stat = 1 # 1 for dev, 0 for production, whether the source file is checke$
  #apc.include_once_override = 1 # Use PHP5.3+ for include_once optimization
  </code></pre>
  
  <p>Thanks in advance and sorry for my bad English,</p>
