Failed to send data from php code via AJAX and JSON response does not come

From that article:

@Admin

You can enable PHP error messages from the control panel:

1. Login to your control panel.
2. Go to Alter PHP Config.
3. Select the domain name you are trying to debug and click Alter PHP Directives.
4. Set “Display Errors” to “On” and click the Alter PHP Directives to save.

If you refresh the page, you should hopefully see an error message.
