title: Rails server not loading a page
body: <p>I'm working on a Rails 3.2.13 app, and I ran <code>rails server</code>.  </p>
  
  <p>The server works fine, but only until I tried render this page:</p>
  
  <pre><code>localhost:3000/items/1/edit
  </code></pre>
  
  <p>From this point on, any page I try to go to wouldn't get loaded.  The strange thing is, there are no error messages shown on the log.  The log just looks like it stopped responding. </p>
  
  <p>As more background information, this morning I tried switching from sqlite to MySQL, and before that, the rails server worked just fine.  I then gave up on the installation of the mysql gem (because of the <a href="https://stackoverflow.com/questions/17866003/rails-installing-mysql-error-installing-mysql2-error-failed-to-build-gem-nat">error</a>), and went back to my old <code>database.yml</code> and gemfile, so I don't suppose the installation attempt would've affected it.</p>
  
  <p>Does anyone have any idea what is happening?</p>
