I am using Nginx + PHP-FPM to run a Wordpress based site. I have a URL that should return dynamically generated JSON data for use with the DataTables jQuery plugin. The data is returned properly, but with a return code of 404. I think this is a Nginx config issue, but I haven't been able to figure out why. The script 'getTable.php' works properly on the production version of the site which is currently using Apache. Anyone know how I can get this to work on Nginx?

UPDATE: Here are the contents of the script: <?php /** * Connect to Wordpres */ require(dirname(__FILE__) . '/../../../../wp-blog-header.php'); /** * Define temporary array */ $aaData = array(); $aaData['aaData'] = array(); /** * Execute Query */ $query = new WP_Query( array( 'post_type' => 'post', 'posts_per_page' => '-1' ) ); foreach ($query->posts as $post) { array_push( $aaData['aaData'], array( $post->post_title ) ); } /** * Echo JSON encoded array */ echo json_encode($aaData);
