Handsontable saving only 250 rows

Question

I am using handsontable in my application. When i tried to save data, using AJAX and PHP, I am able to get only 250 rows of data. Is there any specific configuration , that i need to change to be able to save all the data from handsontable?I have recently changed my css, does that effect anyway? Please take a look at the code below.

    $("#divButtons").find(".btnSubmit").click(function () {
   $.ajax({
    url: "saveData3.php",
    data: { "data" : $container.data('handsontable').getData()},
     //returns all cells' data
    dataType: 'json',
    type: 'POST',               
    success: function(){......})};

My php

  $post_data = $_POST['data'];
 if (!empty($post_data)) {
  $file = fopen('data_save3.json', 'w+');
  fwrite($file, json_encode($post_data));
  fclose($file);
//echo json_encode('success');
  } 

Thanks in advance

I finally got it to work! I was using a "next" button to save the handsontable data and also to navigate to the next page..Now, I used "save" and "next" buttons respectively. That solved the problem.
