title: Cannot redeclare a function previously declared
body: <p>After I have instaled in my site one script, I have an error:</p>
  
  <pre><code>Fatal error: Cannot redeclare ae_detect_ie() (previously declared in /home/xdesign/public_html/Powerful/config.php:24) in /home/xdesign/public_html/Powerful/config.php on line 29
  </code></pre>
  
  <p>This is the line:</p>
  
  <pre><code>function ae_detect_ie()
  {
      if (isset($_SERVER['HTTP_USER_AGENT']) &amp;&amp; 
      (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false))
          return true;
      else
          return false;
  }
  </code></pre>
  
  <p>I don't understand what I did wrong! </p>
  
  <p>The site: <a href="http://fbswapes.com" rel="nofollow">http://fbswapes.com</a></p>
  
  <p>The same script is working in another host.</p>
