Title: New Email Editor Causing Multiple Errors on Website Last modified: July 31, 2025 --- # New Email Editor Causing Multiple Errors on Website * Resolved [bboyfan](https://wordpress.org/support/users/bboyfan/) * (@bboyfan) * [8 months, 3 weeks ago](https://wordpress.org/support/topic/new-email-editor-causing-multiple-errors-on-website/) * The new email editor is causing several critical issues on our website: 1. Customers encounter an error page after completing checkout. 2. All email-related actions in the backend—such as marking an order as “Completed”— also result in an error page. 3. Customers are not receiving any emails. * I was previously using the “WooCommerce Email Template Customizer Premium” plugin, but the issues occur regardless of whether the plugin is activated or deactivated. * theme : bricks WP :  6.8.2woo : 10.0.4some logs: * 2025/07/31 14:16:01 [error] 39499#39499: *458844 FastCGI sent in stderr: “PHP message: PHP Warning: Undefined array key “theme” in …/public/wp-content/plugins/ woocommerce/packages/email-editor/src/Engine/class-theme-controller.php on line 304; PHP message: PHP Fatal error: Uncaught TypeError: array_merge(): Argument# 1 must be of type array, null given in …/public/wp-content/plugins/woocommerce/ packages/email-editor/src/Engine/class-theme-controller.php:304 * Stack trace: * #0 …/public/wp-content/plugins/woocommerce/packages/email-editor/src/Engine/class- theme-controller.php(304): array_merge(NULL, Array) * #1 …/public/wp-content/plugins/woocommerce/packages/email-editor/src/Engine/class- settings-controller.php(198): Automattic\WooCommerce\EmailEditor\Engine\Theme_Controller- >translate_slug_to_color(‘white’) * #2 …/public/wp-content/plugins/woocommerce/packages/email-editor/src/Integrations/ Core/Renderer/Blocks/class-group.php(67): Automattic\WooCommerce\EmailEditor\ Engine\Settings_Controller->translate_slug_to_color(‘white’) * #3 …/public/wp-content/plugins/woocommerce/packages/email-editor/src/Integrations/ Core/Renderer/Blocks/class-group.php(38): Automattic\W” while reading response header from upstream, client: … server: …, request: “POST /wp-admin/admin.php? page=wc-orders&action=edit&id=58373 HTTP/2.0”, upstream: “fastcgi://unix:/var/ run/php8.2-fpm-wenszucom.sock:”, host: “wenszu.com:64458”, referrer: “…/wp-admin/ admin.php?page=wc-orders&action=edit&id=58373” * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fnew-email-editor-causing-multiple-errors-on-website%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 15 replies - 1 through 15 (of 15 total) * Thread Starter [bboyfan](https://wordpress.org/support/users/bboyfan/) * (@bboyfan) * [8 months, 3 weeks ago](https://wordpress.org/support/topic/new-email-editor-causing-multiple-errors-on-website/#post-18580047) * there is no problem in 9.9.5.

Just to clarify — some themes and plugins, including Bricks, can be incompatible with certain WooCommerce features, especially when there are recent updates. It’s not uncommon for conflicts to occur between Bricks and new theme- related changes in WooCommerce or WordPress. * Since it worked in a previous version, we’ll need to confirm if this is indeed a conflict. Please set up a staging site — you can do this by cloning your live site with a plugin like WP Migrate Guru to a subdomain or directory, or by using your host’s staging feature. * Once the staging site is ready, deactivate all plugins except WooCommerce, enable test mode in your payment plugin, and share the test card details with us so we can run test payments. Then switch your theme to Twenty Twenty-Five (this part is very important). * After that, generate a fresh system status report from the staging site and share it with us. We’ll review the setup and run tests to replicate the issues you mentioned. * Thread Starter [bboyfan](https://wordpress.org/support/users/bboyfan/) * (@bboyfan) * [8 months, 2 weeks ago](https://wordpress.org/support/topic/new-email-editor-causing-multiple-errors-on-website/#post-18584734) * hi [@mosesmedh](https://wordpress.org/support/users/mosesmedh/) * I just finished testing on the staging site, and I can confirm that the issue only occurs when using the **Bricks theme**. There are no errors when switching to the **Twenty Twenty-Five** theme. * By the way, the same error also occurs when using the **Hello theme**. * Plugin Support [LovingBro (woo-hc)](https://wordpress.org/support/users/lovingbro/) * (@lovingbro) * [8 months, 2 weeks ago](https://wordpress.org/support/topic/new-email-editor-causing-multiple-errors-on-website/#post-18585563) * Hi [@bboyfan](https://wordpress.org/support/users/bboyfan/), * Thanks so much for getting back to us with the results of your testing. We appreciate the time you’ve taken to investigate this! * It’s helpful to hear that the issue only occurs when using the Bricks theme and the Hello theme, and not with Twenty Twenty-Five. To better understand the scope, could you confirm if you’ve tested with any other themes besides the default Twenty Twenty-Five or Storefront? Knowing whether the issue happens only with Bricks and Hello or across more themes will help us determine how widespread the conflict may be. * If it’s isolated to those two themes, that does suggest a theme-level conflict with WooCommerce’s Block Email Editor. In that case, I’d recommend reaching out to the Bricks and Hello theme developers directly with your findings, especially since the issue doesn’t occur on older WooCommerce versions or default themes. * Let us know what you find, and we’ll be here to support however we can! * Thread Starter [bboyfan](https://wordpress.org/support/users/bboyfan/) * (@bboyfan) * [8 months, 2 weeks ago](https://wordpress.org/support/topic/new-email-editor-causing-multiple-errors-on-website/#post-18585575) * [@lovingbro](https://wordpress.org/support/users/lovingbro/) I just try Astra and Blocksy there is no promble.

The error occurs in the Theme Controller when it tries to merge arrays but receives null values for the “theme” key. Our development team is aware and are working on a fix. * As a workaround, you can temporarily disable the new email editor features: - Go to WooCommerce → Settings → Advanced → Features - Look for email-related feature flags and disable them - This should revert to the older email system while the issue is resolved * I hope that helps.
