title: How to add an iframe to Wordpress sidebar?
body: <p>I am using the default TwentyEleven theme, and I added the following code to sidebar.php, but it does not work (I get a 310 error)</p>
  
  <pre><code>&lt;iframe src="frame.html" name="test" height="600" width="180"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>iframe.html is located in /themes/twentyeleven folder, so it should be working (at least on a regular website). </p>
  
  <p>Is it necessary to use some kind of widget plugin in order to get it to work. What can be preventing the iframe from showing up on the website? </p>
  
  <p>Thank you. </p>
