title: I'm getting dozens of "Failed loading" errors in cgi_error_log daily - what do they mean?
body: <p>I'm seeing dozens of entries, daily, in my cgi_error_log file like this:</p>
  
  <pre><code>20151214T183710: www.example/index.php
  Failed loading /usr/local/lib/ioncube/ioncube_loader_lin_5.2.so:  /usr/local/lib/ioncube/ioncube_loader_lin_5.2.so: wrong ELF class: ELFCLASS32
  Failed loading /usr/local/Zend/lib/ZendExtensionManager.so:  /usr/local/Zend/lib/ZendExtensionManager.so: wrong ELF class: ELFCLASS32
  </code></pre>
  
  <p>I changed the URL in the error message because the site is not yet ready for the public and I don't want any links to the site or even text in posts like this laying around.</p>
  
  <p>As the site is still in testing, these messages are coming from my accessing pages and all of the pages have loaded correctly.</p>
  
  <p>What does this message mean? I have no clue other than that ioncube is some sort of PHP Encoder.</p>
  
  <p>Could this have something to do with the 32bit version of ioncube being run on a 64bit system? I've found references to that sort of problem.</p>
  
  <p>Did some more digging - could this be happening because the version of PHP on the server is not 5.2? Error about ioncube shows 4.2 in the file name.</p>
  
  <p>The version I'm using on the server if 5.5. They have 5.3 and 5.6.</p>
  
  <p>If they had 5.2 I'd give it a try but it is not available.</p>
  
  <p>More digging - found this set in my php.ini file for all my sites.</p>
  
  <pre><code>[Zend]
  zend_extension = /usr/local/lib/ioncube/ioncube_loader_lin_5.2.so

  zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so
  </code></pre>
  
  <p>So - do I need to install newer versions of one or more of the items listed above?</p>
  
  <p>If so - where do I start and can I do it myself or does the hosting company staff have to do it?</p>
