title: All the IIS sites are already configured by some other version of ColdFusion
body: <p>We recently did an update to 2016 for ColdFusion. After the update my application was not working. It shows <strong>Access Forbidden</strong> error. I checked the <code>WS.config</code> file to see if ColdFusion and IIS are connected. At that time I could see it was empty. When I tried to add it then it shows the error <strong>All the IIS sites are already configured by some other version of ColdFusion</strong>.</p>
  <p>Can anyone please help me with this problem?</p>
