Title: possible bug Last modified: March 16, 2022 --- # possible bug * Resolved [ohg123](https://wordpress.org/support/users/ohg123/) * (@ohg123) * [4 years, 3 months ago](https://wordpress.org/support/topic/possible-bug-37/) * so my online store has been setup and functioning since october 2021. However, i noticed that for 3 of my orders there was no shipping charged at all when there should have been. they were not 3 in a row nor were they unusual in any other way. * i have replicated the cart contents and tried on several browsers and cannot replicate this problem. I believe there may have been a bug but rather than annoy my customers to refund and reorder i have just sent the orders and lost out on the shipping charge. * What should I do? How do I report this possible bug? * ALSO shipping rate inputs wont let me use the ‘[‘ or ‘]’ and call them illegal characters for min_fee and max_fee parameters. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fpossible-bug-37%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 10 replies - 1 through 10 (of 10 total) * [Mirko P.](https://wordpress.org/support/users/rainfallnixfig/) * (@rainfallnixfig) * [4 years, 3 months ago](https://wordpress.org/support/topic/possible-bug-37/#post-15462881) * Hello [@ohg123](https://wordpress.org/support/users/ohg123/), * Thank you for reaching out! * There have not been reports of issues with the built-in shipping functionality of WooCommerce core. This is usually caused by conflicts with the theme or plugins not being updated or no longer compatible with WooCommerce. Read more about plugin and theme conflicts in our [Self-Service Guide](https://docs.woocommerce.com/document/woocommerce-self-service-guide/). * In order to troubleshoot this further kindly provide us the following: - **System Status**: You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”. Once you’ve done that, paste it here in your response. - **Screenshots of your shipping settings**: Please include any error message you may encounter. We recommend [https://snipboard.io](https://snipboard.io) or [https://imgbb.com/](https://imgbb.com/) for easily sharing screenshots on the thread. * We look forward to hearing back from you. * Thread

(e.g. same product, same payment method etc…) It’s a little difficult to troubleshoot unless you can replicate the issue. However, looking at your system status, there are a few things I’d like to point out: * 1) Endurance Page Cache: by Mike Hansen – 2.2: When a caching plugin is enabled on your site, it’s recommended to exclude Cart, My Account, and Checkout pages: [https://woocommerce.com/document/configuring-caching-plugins/](https://woocommerce.com/document/configuring-caching-plugins/) * 2) WC Database Version: 6.2.1: your database needs to be updated – it needs to match the WooCommerce version. You can update & verify database from **WooCommerce > Status > Tools**. I’d suggest making a backup before running those commands: [https://woocommerce.com/document/backup-wordpress-content/](https://woocommerce.com/document/backup-wordpress-content/) * Link to image: [https://snipboard.io/jhRt6r.jpg](https://snipboard.io/jhRt6r.jpg) * Thread Starter [ohg123](https://wordpress.org/support/users/ohg123/) * (@ohg123) * [4 years, 3 months ago](https://wordpress.org/support/topic/possible-bug-37/#post-15472200) * I backed up and updated the database and it just happened again. * Also I dont see that plugin Endurance Page Cache: by Mike Hansen – 2.2 installed * aare you saying i should add it? * [hegenberg](https://wordpress.org/support/users/hegenberg/) * (@hegenberg) * [4 years, 3 months ago](https://wordpress.org/support/topic/possible-bug-37/#post-15473497) * Hi [@maykato](https://wordpress.org/support/users/maykato/) * The Endurance Page Cache is listed on your System Status. It is a “Must-Use” plugin, and it was probably installed by your hosting service. You might be able to find it on your plugins dashboard under the [“Must-Use” tab](https://wisdmlabs.com/site/wp-content/uploads/2015/09/wordpress-must-use-plugins.jpg). You might want to check with your hosting service if they can remove the pages mentioned above from caching settings. * Additionally, please let us know if there are any fatal error logs on your site: * Go to _WooCommerce → Status → Logs_ * Choose a log from the drop-down labeled` fatal-errors.log` * Click **View**` * Regards, * Thread Starter [ohg123](https://wordpress.org/support/users/ohg123/) * (@ohg123) * [4 years, 3 months ago](https://wordpress.org/support/topic/possible-bug-37/#post-15473525) * yes here is the fatal error log! * ``` 2022-03-08T13:25:42+00:00 CRITICAL Uncaught TypeError: array_column(): Argument #1 ($array) must be of type array, string given in /home2/rattleu0/public_html/wp-content/plugins/woocommerce/packages/woocommerce-admin/src/RemoteInboxNotifications/Transformers/ArrayColumn.php:27 Stack trace: #0 /home2/rattleu0/public_html/wp-content/plugins/woocommerce/packages/woocommerce-admin/src/RemoteInboxNotifications/Transformers/ArrayColumn.php(27): array_column('', 'slug') #1 /home2/rattleu0/public_html/wp-content/plugins/woocommerce/packages/woocommerce-admin/src/RemoteInboxNotifications/TransformerService.php(59): Automattic\WooCommerce\Admin\RemoteInboxNotifications\Transformers\ArrayColumn->transform('', Object(stdClass), '') #2 /home2/rattleu0/public_html/wp-content/plugins/woocommerce/packages/woocommerce-admin/src/RemoteInboxNotifications/OptionRuleProcessor.php(45): Automattic\WooCommerce\Admin\RemoteInboxNotifications\TransformerService::apply('', Array, '') #3 /home2/rattleu0/public_html/wp-content/plugins/woocommerce/packages/woocommerce-admin/src/RemoteInboxNotifications/RuleEvaluator.php(67): Automattic\WooCommerce\Admin\RemoteInboxNotifications\OptionRuleProcessor->process(Object(stdClass), NULL) #4 /home2/rattleu0/public_html/wp-content/plugins/woocommerce/packages/woocommerce-admin/src/Features/RemoteFreeExtensions/EvaluateExtension.php(27): Automattic\WooCommerce\Admin\RemoteInboxNotifications\RuleEvaluator->evaluate(Array) #5 /home2/rattleu0/public_html/wp-content/plugins/woocommerce/packages/woocommerce-admin/src/Features/RemoteFreeExtensions/Init.php(47): Automattic\WooCommerce\Admin\Features\RemoteFreeExtensions\EvaluateExtension::evaluate(Object(stdClass)) #6 /home2/rattleu0/public_html/wp-content/plugins/woocommerce/packages/woocommerce-admin/src/API/OnboardingFreeExtensions.php(75): Automattic\WooCommerce\Admin\Features\RemoteFreeExtensions\Init::get_extensions() #7 /home2/rattleu0/public_html/wp-includes/rest-api/class-wp-rest-server.php(1141): Automattic\WooCommerce\Admin\API\OnboardingFreeExtensions->get_available_extensions(Object(WP_REST_Request)) #8 /home2/rattleu0/public_html/wp-includes/rest-api/class-wp-rest-server.php(988): WP_REST_Server->respond_to_request(Object(WP_REST_Request), '/wc-admin/onboa...', Array, NULL) #9 /home2/rattleu0/public_html/wp-includes/rest-api/class-wp-rest-server.php(414): WP_REST_Server->dispatch(Object(WP_REST_Request)) #10 /home2/rattleu0/public_html/wp-includes/rest-api.php(386): WP_REST_Server->serve_request('/wc-admin/onboa...') #11 /home2/rattleu0/public_html/wp-includes/class-wp-hook.php(307): rest_api_loaded(Object(WP)) #12 /home2/rattleu0/public_html/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters(NULL, Array) #13 /home2/rattleu0/public_html/wp-includes/plugin.php(522): WP_Hook->do_action(Array) #14 /home2/rattleu0/public_html/wp-includes/class-wp.php(396): do_action_ref_array('parse_request', Array) #15 /home2/rattleu0/public_html/wp-includes/class-wp.php(758): WP->parse_request('') #16 /home2/rattleu0/public_html/wp-includes/functions.php(1310): WP->main('') #17 /home2/rattleu0/public_html/wp-blog-header.php(16): wp() #18 /home2/rattleu0/public_html/index.php(17): require('/home2/rattleu0...') #19 {main} thrown in /home2/rattleu0/public_html/wp-content/plugins/woocommerce/packages/woocommerce-admin/src/RemoteInboxNotifications/Transformers/ArrayColumn.php on line 27 ``` * [Mirko P.](https://wordpress.org/support/users/rainfallnixfig/) * (@rainfallnixfig) * [4 years, 3 months ago](https://wordpress.org/support/topic/possible-bug-37/#post-15473865) * Hi there, * Thank you for sharing that error log which gives me no particular reason to think it is associated with the issue in question. * In order to troubleshoot this further would you mind providing us the following screenshots: * 1) Of the order where we can see the shipping address.
