How to fix AJAX HTTP request which was terminated abnormally? I keep getting this AJAX error message every time when I add taxonomy terms or open view pages with AJAX, to name a few.

An AJAX HTTP request terminated abnormally.
Debugging information follows.
Path: /system/ajax
StatusText: error
ResponseText: 
ReadyState: 4


Any suggestions to how I can resolve the problem? I'm using the dev desktop.
This issue sounds like yours: Drupal alerts "An AJAX HTTP request terminated abnormally" during normal site operation, confusing site visitors/editors
