To change the order need to do some changes in options.php file
Go to options.php file
at line no 775 you will find the array of section content like in order below
1 => array( 'section_title' => 'why choose us', 2 => array( 'section_title' => 'Popular Destination', 3 => array( 'section_title' => 'Special Ofer for you',
Now to change the order, you need to move the array to that position.
