title: joomla article editor not working
body: <p>I have been developing a new version of my Joomla website on a test server. When I copy the database over to the live site I can't edit any of my articles. When I click on an article to edit it, I get a white screen with just fields for the title, category, section and two or three others, but no content field. there is also no formatting on the page. I am pretty sure I have copied across all the new files I added, so I'm not sure what the problem is. </p>
  
  <p>The website is working fine otherwise, and I have tried using different editors and no editor at all.</p>
  
  <p>Can anyone help?</p>
  
  <p>Many thanks,</p>
  
  <p>Ben</p>
