title: Joomla 1.5 to 2.5 with Jupgrade. "undefined migrating error"
body: <p>I've try to migrate a website in Joomla from 1.5 to 2.5 using jUpgrade but I've receive the "undefined migrating" error.</p>
  
  <p><img src="https://i.stack.imgur.com/3CeIg.png" alt="&quot;undefined migrating&quot; error"></p>
  
  <p>The files was correctly transferred, but there's no change to the db, and when I try to log on <code>website.com/jupgrade</code>, I land on a page saying "please delete installation folder" and no db was transferred/created (so I have to create it manually and create menu, article, etc. wasting so much time!)</p>
  
  <p>Please help. I have already tried removing folder and changing <code>tmp</code> to 777 permission (with <code>chmod</code>) and nothing changed!</p>
