title: PHP script not executing
body: <p>I have a form with 1222 fields (I know the number is large, but it's a form for saving translations). When I submit the form, the script is not executing. I get no error message and the error log is empty. Even if the script I post to contains only an echo command, nothing is executed and all I see is a blank page.</p>
  
  <p>I am quite sure this is a PHP setting problem, as the form can be submitted without any problems on other servers. Can anyone shed some light on what the issue could be?</p>
  
  <p>The HTML is:</p>
  
  <pre><code>&lt;form action="test.php" method="post"&gt;
      &lt;input type="text" name="account-form-282f96c7d1ed98d24606d209dcad9842" value=""/&gt;
      &lt;!-- 1221 more inputs with different names, but format is the same as above --&gt;
      &lt;input type="submit" name="submitBT" value="Save"/&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>test.php:</p>
  
  <pre><code>&lt;?php
  echo(1);
  ?&gt;
  </code></pre>
  
  <p>Edit 1:
  If I simplify the input names, e.g.: input_1, input_2 etc. the submit works fine. </p>
  
  <p>Edit 2: 
  I noticed I receive a 406 Not Acceptable HTTP response.</p>
