I’m pretty new to Drupal. After reading two Drupal books finally get my hands dirty and start building my first Drupal Site. I installed the Xampp 1.7.2 on my Windows machine, it comes with PHP 5.3 and MySQL 5.1.37. After the Drupal installation I also downloaded the Views 6.x-2.7 Module from Drupal Website.

When I create a new View as a node type, in the Edit View the Ajax error error keeps popping up after clicking on any of the links.

An error occurred at /admin/build/views/ajax/display/card/default/display_title.
An error occurred at /admin/build/views/ajax/display/card/page_1/path.

I spent an hour googling it and finally the solution. http://drupal.org/node/452384

There is an extra “&” in the function parameter. Removing it fixes the problem :D

views/includes/admin.inc

on line 1559:
function views_ui_ajax_form($js, $key, &$view, $display_id) {

to:
function views_ui_ajax_form($js, $key, $view, $display_id) {
