This doesn’t affect actual email delivery. Please contact the extension author for assistance.” * This affects the following templates: - New Order - POS Refunded Order - POS Completed Order Viewing 12 replies - 1 through 12 (of 12 total) * [Moses M.

I understand you’re having trouble with email delivery, and I know how frustrating that can be. * To better understand the issue you’re facing, could you clarify whether you’re trying to send emails manually from WooCommerce? WooCommerce doesn’t support manual email sending by default. * Also, please share your **System Status Report** so we can take a closer look. You can find it by going to **WooCommerce > Status > Get system report > Copy for support**, then paste the report at [gist.github.com](https://gist.github.com) and share the link here. * Thread Starter [smhcis](https://wordpress.org/support/users/smhcis/) * (@smhcis) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/error-rendering-the-email-preview/#post-18560539) * [@mosesmedh](https://wordpress.org/support/users/mosesmedh/), * I am trying to PREVIEW the email template under WooCommerce > Settings > Emails, but I keep getting the following error message: “There was an error rendering the email preview. This doesn’t affect actual email delivery. Please contact the extension author for assistance.” * If I click the “Send a test email” button it tells me, “There was an error rendering an email preview.” * Also, this does not happen with all the email templates, only with the following: - New Order - POS Refunded Order - POS Completed Order * [Mahfuzur Rahman](https://wordpress.org/support/users/mahfuzurwp/) * (@mahfuzurwp) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/error-rendering-the-email-preview/#post-18561002) * Hi [@smhcis](https://wordpress.org/support/users/smhcis/), * Thanks for the clarification! * We’ve tested this on our end and haven’t been able to replicate the issue, so we’ll need a bit more information to investigate further. * Please share the following: 1. Your **System Status Report** from **WooCommerce → Status → Get system report**. You can paste it via [Pastebin](https://pastebin.com) or [Gist](https://gist.github.com). 2. Any **related fatal errors** from **WooCommerce → Status → Logs**. 3. A **screenshot of your browser’s console** while the error appears. This can help us catch any JavaScript-related issues. * Thank you. * Thread Starter [smhcis](https://wordpress.org/support/users/smhcis/) * (@smhcis) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/error-rendering-the-email-preview/#post-18564922) * **System Status Report** * [https://gist.github.com/smahigdon/883473b79bc0e53d564db2d36874fc3a](https://gist.github.com/smahigdon/883473b79bc0e53d564db2d36874fc3a) * **Logs** * No recent fatal errors, but this is the entry under the “plugin-woocommerce” log. * ```wp-block-code 2025-07-21T20:14:31+00:00 Debug Attempted to determine the edit URL for order 12345, however the order does not exist.2025-07-21T20:14:31+00:00 Debug Attempted to determine the edit URL for order 12345, however the order does not exist. ``` * **Screenshot** * ![](https://i0.wp.com/www.divieight.com/wp-content/uploads/2025/07/Screenshot- 2025-07-21-152221.png?ssl=1) - This reply was modified 10 months, 3 weeks ago by [smhcis](https://wordpress.org/support/users/smhcis/). * [Sai (woo-hc)](https://wordpress.org/support/users/saivutukuru/) * (@saivutukuru) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/error-rendering-the-email-preview/#post-18565307) * Thanks for the details. * I checked your site’s System Status Report, and I noticed you’re using the ** WooCommerce POS plugin by kilbot (v0.4.28)**. This plugin adds custom email templates like “POS Refunded Order” and “POS Completed Order,” which don’t come from WooCommerce core. * Likely, these templates aren’t fully compatible with the current email preview system in WooCommerce, especially if they use older template structures or are missing hooks. That could be why the email preview works for default templates, but not for these POS-related ones. * As a next step, I recommend temporarily disabling the WooCommerce POS plugin and checking if the previews load correctly afterward. If that resolves it, the issue is likely with how the POS plugin registers or renders its email templates. * Let us know how it goes, and if needed, we’d suggest reaching out to the plugin developer for compatibility updates. * [kilbot](https://wordpress.org/support/users/kilbot/) * (@kilbot) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/error-rendering-the-email-preview/#post-18565518) * Hi [@smhcis](https://wordpress.org/support/users/smhcis/) & [@saivutukuru](https://wordpress.org/support/users/saivutukuru/), I am the developer of WooCommerce POS. Just a short note to say that my plugin doesn’t add any email templates. It’s possible they come from another POS plugin, or perhaps they were added by the user. * [Moses M.

Do you recall which plugin you used to enable this functionality? * Thread Starter [smhcis](https://wordpress.org/support/users/smhcis/) * (@smhcis) * [10 months, 2 weeks ago](https://wordpress.org/support/topic/error-rendering-the-email-preview/#post-18569704) * [@mosesmedh](https://wordpress.org/support/users/mosesmedh/), I think you may have read the wrong system report. I do not use the WooCommerce POS plugin on any of my websites. * I reviewed my other websites and found 3 of them have these same POS Refunded Order and POS Completed order. I cannot find a WooCommerce addon that is common between the three of them. * I tried deactivating all plugins except for WooCommerce and the POS templates/ settings were still there. * [Moses M.

Could you please confirm whether you’re using the same theme and plugins on this site as on the other one? * By default, WooCommerce does not include email templates for **POS Refunded Order** or **POS Completed Order** — these typically come from a POS plugin or something similar. * To help investigate further, please provide the following: - A screenshot of **WooCommerce > Settings > Emails** - A full screenshot of each of those email templates after clicking **Manage** * You can use a tool like [Snipboard](https://snipboard.io) to share the screenshots.

This doesn’t affect actual email delivery. Please contact the extension author for assistance.”** — typically indicates that a third-party plugin or theme is interfering with the email preview functionality. This does not impact the actual sending of order emails but affects the ability to generate the preview within the admin area. * To isolate the cause, I recommend performing a complete conflict test by temporarily switching to the **Storefront** theme and deactivating all plugins except **WooCommerce**. Then, check if the email preview works correctly. Also I would suggest to make sure you are using WooCommerce latest version 10.0.4 * If you prefer not to test on your live site, you can create a staging site (a copy of your site used for safe testing). If your host doesn’t already provide staging functionality, plugins like [WP Staging](https://wordpress.org/plugins/wp-staging/) can help with that. * Once the conflict test is done, you can re-enable your theme and plugins one at a time to identify which one may be causing the issue. * Plugin Support [Chris Moreira – a11n](https://wordpress.org/support/users/chrism245/) * (@chrism245) * [9 months, 4 weeks ago](https://wordpress.org/support/topic/error-rendering-the-email-preview/#post-18599669) * Since we didn’t hear back from you, I’ll mark this as resolved for now.
