Am using the ajax file upload plugin from PHP Letter and am using jQuery 1.6.2.The files upload properly, but am unable to user the JSON data returned from the php script, when i check the javascript error consolse am i greeted with this error,
"Uncaught TypeError: Object function (a,b){return new e.fn.init(a,b,h)} has no method 'handleError'"
in chrome and
"jQuery.handleError is not a function"
in firefox.
Does any one have a similar experience?

It was when you are trying to use this with latest version of jQuery. handleError function is depreciated from library upper then V 1.5. I resolve it by just adding this function in my ajaxfileupload.js file.
handleError: function( s, xhr, status, e ) {
// If a local callback was specified, fire it
if ( s.error ) {
s.error.call( s.context || window, xhr, status, e );
}
// Fire the global callback
if ( s.global ) {
(s.context ? jQuery(s.context) : jQuery.event).trigger( "ajaxError", [xhr, s, e] );
}
}
and it works fine for me. Also, if you try to use any ajaxSubmit() on same page it will wont work, so i use normal form submit with ajxfileupload. if any one can help in same way please let me know.

Modern jQuery's do not have the jQuery.handleError(s, xml, status, e) method.
Therefore, in case of an error, the file uploader hangs all javascripts.
This uploader script is small, elegant and nice. However, it's rather old and jQuery has completely redesigned ajax handing since then. Next time, I'll try to use a modern complex script with a progress bar and drag-and-drop support: http://valums.com/ajax-upload/
Otherwise, for legacy code or simplicity reasons, you'll find this fix of ajaxfileupload.js (Version 2.1) useful: Note that global "ajaxError" event is not supported.

I also use this plugin and there is some incompability with new versions of jQuery. I use jquery-1.9.1.js on my project.
The plugin is used with jquery-1.2.1.js .
I have found a solution on a Chinese website : http://chen-h.iteye.com/blog/1769457 I have tested this version and it works. Callbacks are now okay.
I don't speak Chinese but I imagine the developer has converted this plugin for new version of Jquery.

The example uses jQuery 1.2.1;
http://www.phpletter.com/javascript/jquery.js
the jQuery.handleError() was removed a while back, I'm not sure when.
You need to use an older jQuery version, update the script yourself or try to find an up to date script. Try http://valums.com/ajax-upload/ or have a search for a few but just remember to check their last update date!
