Title: Payments not working – AUTHENTICATION_ERROR Last modified: April 24, 2018 --- # Payments not working – AUTHENTICATION_ERROR * Resolved [myhreco](https://wordpress.org/support/users/myhreco/) * (@myhreco) * [8 years ago](https://wordpress.org/support/topic/payments-not-working-authentication_error/) * I’m having the same problem with payments not working that somebody else was having, but reading the other thread, none of the resolutions worked or applied. Square payments aren’t going through – full error message is below. * All requirements are good on my system – SQL 5.6, PHP 7.0, I tried linking and unlinking to square and nothing has worked. * ERROR MESSAGE: * Array ( [0] => stdClass Object ( [category] => AUTHENTICATION_ERROR [code] = > UNAUTHORIZED [detail] => This request could not be authorized. ) ) Order status changed from Pending payment to Failed.

Could you also try disconnecting the actual plugin and reactivating it to see if it helps? * Could you also copy/paste your system status report? * Thread Starter [myhreco](https://wordpress.org/support/users/myhreco/) * (@myhreco) * [8 years ago](https://wordpress.org/support/topic/payments-not-working-authentication_error/#post-10222587) * Hi, * I just tried deactivating and reactivating the Square plugin and it didn’t change anything. I turned on error logging during this last test, and below is what the error log is showing. Will get system report too if below doesn’t help. * 2018-02-22T15:55:15+00:00 CRITICAL Uncaught TypeError: Argument 1 passed to WC_Square_Sync_To_Square:: sync_inventory() must be an instance of WC_Product, boolean given, called in / home/micheles/public_html/wp-content/plugins/woocommerce-square/includes/class- wc-square-sync-to-square-wp-hooks.php on line 287 and defined in /home/micheles/ public_html/wp-content/plugins/woocommerce-square/includes/class-wc-square-sync- to-square.php:221 Stack trace: #0 /home/micheles/public_html/wp-content/plugins/ woocommerce-square/includes/class-wc-square-sync-to-square-wp-hooks.php(287): WC_Square_Sync_To_Square->sync_inventory(false) #1 /home/micheles/public_html/ wp-includes/class-wp-hook.php(300): WC_Square_Sync_To_Square_WordPress_Hooks- >on_variation_set_stock(Object(WC_Product_Variation)) #2 /home/micheles/public_html/ wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(”, Array) #3 /home/ micheles/public_html/wp-includes/plugin.php(515): WP_Hook->do_action(Array) # 4 /home/micheles/public_html/wp-cron.php(117): do_action_ref_array(‘wc_square_on_va…’ * 2018-02-23T06:13:04+00:00 CRITICAL Uncaught TypeError: Argument 1 passed to WC_Square_Sync_To_Square:: sync_inventory() must be an instance of WC_Product, boolean given, called in / home/micheles/public_html/wp-content/plugins/woocommerce-square/includes/class- wc-square-sync-to-square-wp-hooks.php on line 287 and defined in /home/micheles/ public_html/wp-content/plugins/woocommerce-square/includes/class-wc-square-sync- to-square.php:221 Stack trace: #0 /home/micheles/public_html/wp-content/plugins/ woocommerce-square/includes/class-wc-square-sync-to-square-wp-hooks.php(287): WC_Square_Sync_To_Square->sync_inventory(false) #1 /home/micheles/public_html/ wp-includes/class-wp-hook.php(300): WC_Square_Sync_To_Square_WordPress_Hooks- >on_variation_set_stock(Object(WC_Product_Variation)) #2 /home/micheles/public_html/ wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(”, Array) #3 /home/ micheles/public_html/wp-includes/plugin.php(515): WP_Hook->do_action(Array) # 4 /home/micheles/public_html/wp-cron.php(117): do_action_ref_array(‘wc_square_on_va…’ * Plugin Support [dougaitken](https://wordpress.org/support/users/dougaitken/) * (@dougaitken) * Automattic Happiness Engineer * [8 years ago](https://wordpress.org/support/topic/payments-not-working-authentication_error/#post-10243941) * Hi [@myhreco](https://wordpress.org/support/users/myhreco/) * That doesn’t look good, were you able to resolve this? Can you confirm you’re on the latest version of the extension, `1.0.29`, please? * Have you reached out to us at WooCommerce.com about this? We can help with Square queries there. * Thanks, * Thread Starter [myhreco](https://wordpress.org/support/users/myhreco/) * (@myhreco) * [8 years ago](https://wordpress.org/support/topic/payments-not-working-authentication_error/#post-10244821) * Hi – no, it hasn’t been resolved yet. We just started using the PayPal plugin instead of Square for now. I checked and yes, I’ve been testing using the latest Ver. 1.0.29 of the plugin. Where on WooCommerce.com would I submit a question about this plugin – in the support ticket section? * Thanks for any info. * Plugin Support [dougaitken](https://wordpress.org/support/users/dougaitken/) * (@dougaitken) * Automattic Happiness Engineer * [8 years ago](https://wordpress.org/support/topic/payments-not-working-authentication_error/#post-10245508) * Hi again [@myhreco](https://wordpress.org/support/users/myhreco/) * Okay, if you head to WooCommerce.com, you can submit a ticket via [https://woocommerce.com/my-account/create-a-ticket/](https://woocommerce.com/my-account/create-a-ticket/) * If you don’t have the option to select Square from the WooCommercee Extensions menu then please “purchase” the extension for free on the site, and you’ll then have that option – [https://www.woocommerce.com/products/square/](https://www.woocommerce.com/products/square/) * Please be sure to include details and a system status report when you do. * Thanks, * Plugin Support [dougaitken](https://wordpress.org/support/users/dougaitken/) * (@dougaitken) * Automattic Happiness Engineer * [8 years ago](https://wordpress.org/support/topic/payments-not-working-authentication_error/#post-10274875) * Hi [@myhreco](https://wordpress.org/support/users/myhreco/) * Did you get a ticket to us for help with the problem? * We haven’t heard back from you in a while, so I’m going to mark this as resolved– if you have any further questions, please let us know. * Thanks, * Thread Starter [myhreco](https://wordpress.org/support/users/myhreco/) * (@myhreco) * [8 years ago](https://wordpress.org/support/topic/payments-not-working-authentication_error/#post-10275900) * Yes, I moved my question over to a WooCommerce support ticket. Problem is resolved, but I have no idea how it happened. I just deleted and reinstalled the plugin 3 or 4 times, and then it suddenly was working. So, I have no solutions for other people to try if they have this issue, but I’m all set now. Thanks!
