‘post_status’ => ‘publish’,

Test Website:
As a web developer you need to have a habit of seperating the live website from your testing and developments. Always have two installs of any WordPress on your websites. This is crucial to ensure that turning on error reporting won’t cause your scripts to terminate.
WPBD Error Reporting:

global $wpdb;
// Before running your query:
$wpdb->show_errors = TRUE;
$result = $wpdb->get_results(“SELECT field_value FROM table_name”);
if(! $result){
$wpdb->print_error();
// Or you can choose to show the last tried query.
echo $wpdb->last_query;
}
Server Log Errors:
There would be times where neither PHP or WordPress would be successful in catching some coding errors. For instance, when your script exceeds the maximum allowed run time, you won’t get any PHP error. You would just get a popup saying ‘Internal Server Error’. Instead, go to your error log, and check if your PHP code or any certain part of your WordPress installation had any errors or did something wrong.
PHP Syntax Checker:
If you are working on a hosting service that limits access to php.ini. file, or it doesn’t let you access error logs, it might make things more complicated. However, there are many capable tools that can help you solve any complications when you get a blank page with no error message.
Disable Browser Cache:
If you are more comfortable on the front-end of the website, then you can try simply disabling the cache of the browser you are working on. This is crucial if you are working on a JavaScript code and it stops updating, or keeps updating but stops showing new errors. In such cases you would need to disable cache. Doing so means that you are requesting your browser to stop working on any old stored files of your website. This also includes JavaScript and CSS files.
