title: phpMyAdmin gives export.php instead of database sql dump
body: <p><strong>Environment</strong></p>
  
  <ul>
  <li>Wamp server 2.5 x64 (MySQL 5.6.17, phpmyadmin4.1.14) on Windows 10 Enterprise x64 (Fresh installation, no major changes since yesterday total installation)</li>
  <li>Full control access to <code>C:\wamp\tmp\</code> folder for windows <code>everyone</code> group, and the folder is not read-only</li>
  </ul>
  
  <p><strong>Problem</strong></p>
  
  <p>When I try to export my database using <code>Export</code> tab, under my database page, It gives me the <code>export.php</code> file, the <code>body</code> part of which is like this:</p>
  
  <pre><code>&lt;body&gt;
      &lt;h1&gt;phpMyAdmin - Error&lt;/h1&gt;
      &lt;p&gt;export.php: Missing parameter: export_type&amp;lt;a href="./doc/html/faq.html#faqmissingparameters" target="documentation"&amp;gt;&amp;lt;img src="themes/dot.gif" title="Documentation" alt="Documentation" class="icon ic_b_help" /&amp;gt;&amp;lt;/a&amp;gt;&lt;br /&gt;&lt;/p&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>But, I expect the <code>.sql</code> dump file!</p>
  
  <p><strong>My effort</strong></p>
  
  <ul>
  <li>I googled for <code>export.php: Missing parameter: export_type</code> with no success.</li>
  <li>I also visited <code>http://localhost/phpmyadmin/doc/html/faq.html#faqmissingparameters</code> for any useful notes, with no success.</li>
  <li>In <code>config.inc.php</code>, the <code>$cfg['PmaAbsoluteUri']</code> directive is empty.</li>
  <li>In <code>php.ini</code> the <code>arg_separator.input</code> directive has value <code>;&amp;</code>.</li>
  </ul>
  
  <p><strong>Edit</strong></p>
  
  <p>Screenshot added, right before pressing <code>Go</code> button</p>
