500（内部服务器错误）ajax调用

Question

Internal error occurs when the site is on server, on localhost it works fine. The code is as given below.

GET http://www.olbx.in/classified/extract_handler_post.php 500 (Internal Server Error)x.ajaxTransport.send @ jquery-1.10.2.min.js:6x.extend.ajax @ jquery-1.10.2.min.js:6(anonymous function) @ books-classified:281(anonymous function) @ books-classified:345

Increasing the timeout time did not help out

The complete error:

$.ajax({
    type: 'GET',
    url: '../classified/extract_handler_post.php',
    data: SendInfo,
    dataType: 'json',

        for ( i = 0 ; i < count ;i++ ) {

            //if (data['data'][i]['category']=="Books"){
