body: <p>I am running Apache 2.2 with PHP5.3 running a PHP business app. Everything works fine from a business point of view, however I do get an error in my apache error.log</p>
  
  <pre><code>[Thu Nov 01 12:07:17 2012] [error] [client 10.200.8.37] File does not exist: /var/www/webroot/itassistant

  </code></pre>
  
  <p>In my access.log the following is logged:</p>

  </code></pre>
  
  <p>The PHP log gives no errors.</p>
  
  <p>The PHP applications is the only application I am running and my application provider says that this isn't caused by the application.</p>
  
  <p>I am running on an Ubuntu 12.04 server. Can anybody help me find the cause of these errors? How can I find out what is trying to call these non existing items and why </p>
