title: Deployed Solution containing visual web part not showing up in Custom category
body: <p>I have a Password Change visual web part that deploys and functions perfectly on my development server yet on the Integration/Test server the .wsp deploys yet does not show the web part in the pick list "Custom" category for any site.</p>
  
  <p>Integration/Test Central Management Console .wsp file status:</p>
  
  <p>Name: sp2010passwordchange.wsp<br>
  Type: Core Solution<br>

  <p>Elements file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
     &lt;Elements xmlns="http://schemas.microsoft.com/sharepoint/" &gt;
       &lt;Module Name="PasswordChange" List="113" Url="_catalogs/wp"&gt;
         &lt;File Path="PasswordChange\PasswordChange.webpart" Url="PasswordChange.webpart" Type="GhostableInLibrary" &gt;
           &lt;Property Name="Group" Value="Custom" /&gt;
         &lt;/File&gt;
      &lt;/Module&gt;
  &lt;/Elements&gt;
  </code></pre>
  
  <p>Also -- the web part does not show up the the web part gallery as well.</p>
  
  <p><hr>
  So my questions are:<br>
   What are the most common reasons for this failure?
   Am I missing some additional Site deployment steps?</p>
  
  <p>Thanks!</p>
