Could this be because I haven’t updated to the newest WordPress? - This reply was modified 7 years, 4 months ago by [chelseavca](https://wordpress.org/support/users/chelseavca/). * Plugin Contributor [Ben Ritner – Kadence WP](https://wordpress.org/support/users/britner/) * (@britner) * [7 years, 4 months ago](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/#post-11061609) * Latest WordPress shouldn’t matter unless the plugin you updated depend on it. * Are you using “WP Super Cache” * Have you tried with another browser? * Thread Starter [chelseavca](https://wordpress.org/support/users/chelseavca/) * (@chelseavca) * [7 years, 4 months ago](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/#post-11061632) * I am using WP Super Cache!

No worries – last question though! The emails get sent correctly but in Gmail there is no CSS but Hotmail shows the correct design. Would you know why this is? It started happening just before installing the plugin too, was hoping this would fix it but it didn’t. * Plugin Contributor [Ben Ritner – Kadence WP](https://wordpress.org/support/users/britner/) * (@britner) * [7 years, 4 months ago](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/#post-11061755) * In your woocommerce email settings can you make sure all the emails are being set as html and not plain text. * Do you know if your theme or any other plugin is editing the email templates? * Ben * Thread Starter [chelseavca](https://wordpress.org/support/users/chelseavca/) * (@chelseavca) * [7 years, 4 months ago](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/#post-11061838) * It’s set to HTML already which is why Hotmail shows it properly. I had created a custom template a while back, however I just deleted them and resent the emails and they’re still showing up not formatted in Gmail… * Plugin Contributor [Ben Ritner – Kadence WP](https://wordpress.org/support/users/britner/) * (@britner) * [7 years, 4 months ago](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/#post-11062017) * Can you send one of the emails to [info@kadencethemes.com](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/info@kadencethemes.com?output_format=md) so I can see whats being output? * Thread Starter [chelseavca](https://wordpress.org/support/users/chelseavca/) * (@chelseavca) * [7 years, 4 months ago](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/#post-11062198) * You bet!

Since that was just a forward and not direct from your site is it possible for you to send me an email from your site so I can see what you are seeing when you open with a hotmail account? * Ben * Thread Starter [chelseavca](https://wordpress.org/support/users/chelseavca/) * (@chelseavca) * [7 years, 4 months ago](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/#post-11062268) * Sent 🙂 * Plugin Contributor [Ben Ritner – Kadence WP](https://wordpress.org/support/users/britner/) * (@britner) * [7 years, 4 months ago](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/#post-11065255) * Thanks, I compared this with emails that test sites and even our live site send out. Something has changed the output on our site, it’s like a template for styles is being overridden. * I suggest you go to woocommerce > status and make sure no template is overriding woocommerce email templates. * Then I would deactivate other woocommerce extensions and then test again. * Ben Viewing 15 replies - 1 through 15 (of 17 total) 1 [2](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/page/2/?output_format=md) [→](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/page/2/?output_format=md) The topic ‘Error: Non-existent changeset UUID.’ is closed to new replies. * ![](https://ps.w.org/kadence-woocommerce-email-designer/assets/icon-256x256.png? rev=3115863) * [Kadence WooCommerce Email Designer](https://wordpress.org/plugins/kadence-woocommerce-email-designer/) * [Frequently Asked Questions](https://wordpress.org/plugins/kadence-woocommerce-email-designer/#faq) * [Support Threads](https://wordpress.org/support/plugin/kadence-woocommerce-email-designer/) * [Active Topics](https://wordpress.org/support/plugin/kadence-woocommerce-email-designer/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/kadence-woocommerce-email-designer/unresolved/) * [Reviews](https://wordpress.org/support/plugin/kadence-woocommerce-email-designer/reviews/) * 17 replies * 4 participants * Last reply from: [Kevin](https://wordpress.org/support/users/jx-3p/) * Last activity: [7 years, 2 months ago](https://wordpress.org/support/topic/error-non-existent-changeset-uuid/page/2/#post-11246160) * Status: not resolved
