I have a Joomla site 2.5.4 and contact form is build using Fabrik plugin. When I submit the contact form I receive a JSON response instead of thank you page.

I have set the form properly from the back-end as well. Please refer image below for details of back-end setup.

Please check JSON response below

{
msg: "Record added/updated",
url: "index.php?option=com_content&view=article&id=24",
baseRedirect: false,
rowid: "0",
redirect_how: "newpage",
width: 300,
height: 300,
x_offset: 0,
y_offset: 0,
title: "",
reset_form: true
}
