title: 500.19 Internal Server Error - RequestFilteringModule config error
body: <p>I'm working on a site built on the <a href="http://telligent.com" rel="nofollow noreferrer">Telligent Community</a> platform. It comes with a zip of the site that I need to setup and build from. I've setup the site and have been working on it, except the default <code>web.config</code> has one thing that breaks the site, unless I comment it out. The line is <code>&lt;requestFiltering allowDoubleEscaping="true" /&gt;</code> in the following section:</p>
  
  <pre><code>&lt;system.webServer&gt;
    &lt;validation validateIntegratedModeConfiguration="false" /&gt;
    &lt;security&gt;
      &lt;requestFiltering allowDoubleEscaping="true" /&gt;
    &lt;/security&gt;
    ... continues ...
  </code></pre>
  
  <p>If I comment out the line, my site works. If not, I get this error:</p>
  
  <pre><code>Config Error
  This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
  </code></pre>
  
  <p>One thing I read was to go to <code>applicationHost.config</code> file located in <code>windows\system32\inetsrv\config</code> and change the following values in <code>&lt;sectionGroup name="system.webServer"&gt;</code> to "Allow":</p>
  
  <pre><code>&lt;section name="handlers" overrideModeDefault="Deny" /&gt;
  &lt;section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Deny" /&gt;
  </code></pre>
  
  <p>I've made the above changes and done an <code>iisreset</code> and I still get the same error. Does anyone have any ideas that will allow this line in my config to work?</p>
