Error happening with client payment through ProSites

Hi There,
Today one of my clients payments via paypal renewed (it was a yearly payment). For some reason I am getting the following error in my error log - it appears that there is some error here with Stripe, even though the payment was through paypal.

2016/01/13 11:35:11 [error] 4271#0: *98901 FastCGI sent in stderr: "PHP message: WordPress database error Unknown column 'subscription_id' in 'field list' for query SELECT customer_id, subscription_id FROM wp_pro_sites_stripe_customers WHERE blog_id = 59 made by do_action('wp_ajax_nopriv_psts_pypl_ipn'), call_user_func_array, ProSites_Gateway_PayPalExpressPro->ipn_handler, ProSites->extend, ProSites_Gateway_Stripe::attempt_manual_reactivation, ProSites_Gateway_Stripe::get_customer_data

Do you know what this error means and how I could fix it?
Thanks
