Live Paypal

Hello, finally going live with Paypal, but once we pass to production we got this error:

Fatal error: Uncaught exception ‘Exception’ with message ‘Preapproval failed: One of the required parameters for subscription is missing’ in /home/fili4360/public_html/wp-content/themes/funding_press/funding/paypal.php:100 Stack trace: #0 /home/fili4360/public_html/wp-content/themes/funding_press/funding/funding.php(347): F_PayPal->get_auth_url(Object(WP_Post), Object(WP_Post), Object(WP_Post)) #1 [internal function]: F_Controller->action_template_redirect(”) #2 /home/fili4360/public_html/wp-includes/plugin.php(505): call_user_func_array(Array, Array) #3 /home/fili4360/public_html/wp-includes/template-loader.php(12): do_action(‘template_redire…’) #4 /home/fili4360/public_html/wp-blog-header.php(16): require_once(‘/home/fili4360/…’) #5 /home/fili4360/public_html/index.php(17): require(‘/home/fili4360/…’) #6 {main} thrown in /home/fili4360/public_html/wp-content/themes/funding_press/funding/paypal.php on line 100
