title: Prestashop New string to translate doesn't appear in my back-office
body: <p>I'm having a very stupid issue with a new string I need to translate. I added it into my theme file :</p>
  
  <p>File: /themes//order-carrier.tpl </p>
  
  <pre><code>{*Displaying a link to CMS page*} 
  {if $carrier.id_carrier == 36} 
      &lt;a href="{$link-&gt;getCMSLink(21)}" target="_blank"&gt;{l s="My new string"}&lt;/a&gt;
  {/if}
  </code></pre>
  
  <p>But when I go to my back-office to translate the string, I can't find this new string (Tools > Translations) ... </p>
  
  <p>I'm using Prestashop 1.4.9 and I disabled Smarty's cache.</p>
