title: opencart default language selection
body: <p>I have set my default language from admin panel to Persian.</p>
  
  <p>Now, every module uses persian language directory by default.</p>
  
  <p>Thought there is one module that still persists in using English as its language. While I have set the translation in corresponding directory in language/persian.</p>
  
  <p>My question is that how can I force the module to use the language/persian instead of language/english?</p>
  
  <p>Here is the beginning of the module's Controller that fetches the language file:</p>
  
  <pre><code>$this-&gt;language-&gt;load('module/trackorder');
  
          $this-&gt;data['heading_title'] = $this-&gt;language-&gt;get('heading_title');
          $this-&gt;data['back'] = $this-&gt;url-&gt;link('common/home');
  .....
  </code></pre>
