Title: Plugin issue blocking all payments Last modified: June 1, 2021 --- # Plugin issue blocking all payments * Resolved [Beats247](https://wordpress.org/support/users/beats247/) * (@beats247) * [4 years, 12 months ago](https://wordpress.org/support/topic/plugin-issue-blocking-all-payments/) * Hello there, I have been using your plugin for a while now and it used to work fine. A few days ago it started blocking all payments on my site though and I ended up losing a lot of potential customers because I just found out about it today… I didn’t update anything on the site though so I don’t know why it just stopped working. Apparently, it’s a bug or incompatibility because it simply closes the WooCommerce PayPal popup window (WC Stripe also didn’t work anymore). I deactivated the plugin now and everything is working again. Could you please check on this? Thank you! * This is the error: * ``` 2021-06-01T11:14:43+00:00 CRITICAL Uncaught TypeError: mysqli::real_connect(): Argument #5 ($port) must be of type ?int, string given in /public_html/wp-includes/wp-db.php:2056 Stack trace: #0 [internal function]: mysqli->real_connect() #1 /public_html/wp-includes/wp-db.php(2056): mysqli_query() #2 /wp-includes/wp-db.php(1945): wpdb->_do_query() #3 /wp-includes/wp-db.php(2695): wpdb->query() #4 /wp-includes/class-wp-query.php(3034): wpdb->get_results() #5 /wp-includes/class-wp-query.php(3465): WP_Query->get_posts() #6 /wp-includes/post.php(2153): WP_Query->query() #7 /wp-content/plugins/woo-manage-fraud-orders/includes/class-wmfo-track-fraud-attempts.php(210): get_posts() #8 /wp-content/plugins/woo-manage-fraud-orders/includes/class-wmfo-track-fraud-attempts.php(108): WMFO_Track_Customers::manage_blacklisted_customers() #9 /wp-includes/class-wp-hook.php(292): WMFO_Track_Customers::manage_blacklisted_customers_checkout() #10 /wp-includes/class-wp-hook.php(316): WP_Hook->apply_filters() #11 /wp-includes/plugin.php(484): WP_Hook->do_action() #12 wp-content/plugins/woocommerce/includes/class-wc-checkout.php(878): do_action() #13 /wp-content/plugins/woocommerce/includes/class-wc-checkout.php(1152): WC_Checkout->validate_checkout() #14 /wp-content/plugins/woocommerce-gateway-paypal-express-checkout/includes/class-wc-gateway-ppec-cart-handler.php(171): WC_Checkout->process_checkout() #15 /wp-includes/class-wp-hook.php(292): WC_Gateway_PPEC_Cart_Handler->wc_ajax_start_checkout() #16 /wp-includes/class-wp-hook.php(316): WP_Hook->apply_filters() #17 /wp-includes/plugin.php(484): WP_Hook->do_action() #18 /wp-content/plugins/woocommerce/includes/class-wc-ajax.php(90): do_action() #19 /wp-includes/class-wp-hook.php(292): WC_AJAX::do_wc_ajax() #20 /wp-includes/class-wp-hook.php(316): WP_Hook->apply_filters() #21 /wp-includes/plugin.php(484): WP_Hook->do_action() #22 /public_html/wp-includes/template-loader.php(13): do_action() #23 /public_html/wp-blog-header.php(19): require_once('/home/517141.cl...') #24 /public_html/index.php(17): require('/home/517141.cl...') #25 {main} thrown in /public_html/wp-includes/wp-db.php on line 2056 ``` * Woo Manage Fraud Orders 2.0.0 WooCommerce v5.3.0 WC PayPal Checkout Gateway v2.1.1 WC Stripe Gateway v5.2.0 Wordpress v5.7.2 Viewing 3 replies - 1 through 3 (of 3 total) * Plugin Author [prasidhda](https://wordpress.org/support/users/prasidhda/) * (@prasidhda) * [4 years, 12 months ago](https://wordpress.org/support/topic/plugin-issue-blocking-all-payments/#post-14510023) * hi [@beats247](https://wordpress.org/support/users/beats247/), Thanks for using the plugin. * It seems the compatibility issue, however I can’t say exactly with which plugin.

I’m busy right now and my website is working without your plugin now. It’s not a compatibility issue with another plugin as the setup has been the same over the past few months and it worked for a while. It then had the checkout issue, updating WordPress fixed it though and then appeared again after a few weeks (nothing has been changed though). I will send you an e-mail as soon as possible so you can check the issue.
