title: %40 on click turns to %2540
body: <p>when the link is clicked containing the @ symbol, the url gives me %40, which is what I want. But once I click it, one second later it changes to %2540 right after I click. The click is within an email, then directed to the site, where %40 changes to %2540. How can I make it stop changing?</p>
  
  <p>it is getting the params like this now:</p>
  
  <pre><code>$email=Yii::app()-&gt;request-&gt;getParam('email');
  </code></pre>
  
  <p>not sure what other information i should provide.</p>
