title: AJAX 500 (Internal Server Error)
body: <p>I have some issue with a web application instance that I migrated recently to the new server. The weird thing is that the instance works locally but when on the server it shows the following on console log:</p>
  
  <pre><code>POST http://subdomain.domain.com/index.php?module=MailManager&amp;view=Index&amp;_operation=folder&amp;_operationarg=open&amp;_folder=INBOX&amp;_page=0 500 (Internal Server Error) 
  send 
  f.extend.ajax 
  f.(anonymous function) 
  MailManager.folder_open 
  MailManager.openCurrentFolder
  MailManager.mainui
  (anonymous function)
  n
  o.fireWith
  e.extend.ready
  c.addEventListener.C
  
  
  POST http://subdomain.domain.com/index.php?module=MailManager&amp;view=Index&amp;_operation=mainui 500 (Internal Server Error) jquery.min.js:4
  send
  f.extend.ajax
  f.(anonymous function)
  (anonymous function)
  </code></pre>
  
  <p>Any help would really be appreciated!
  Thanks</p>
