Ajax-dashboard error <Fixed>

I am getting this error on my site when the site is trying to call up the ajax-dashboard.

Fatal error: Cannot redeclare gen_difference() (previously declared in /virtual/users/e17303-19081/web/ajax-gizmo.php:86) in /virtual/users/e17303-19081/web/ajax-dashboard.php on line 1020

see bottom of page - http://www.letxweather.com/wxindex.php

Thanks for the help,

You may be running an old version of ajax-gizmo.php … try replacing your copy with one from the current Base-USA distribution.

Best regards,

Thanks Ken, that fixed the problem.
