Title: Undefined array key Last modified: April 10, 2024 --- # Undefined array key * Resolved [lisaxdfsjh](https://wordpress.org/support/users/lisaxdfsjh/) * (@lisaxdfsjh) * [2 years, 1 month ago](https://wordpress.org/support/topic/undefined-array-key-47/) * Hi, * on the order confirmation page, I’m receiving the following error message: ** Warning: Undefined array key 0 in /home/.sites/37/site2738444/web/wp-content/ plugins/woocommerce-payments/vendor/automattic/jetpack-sync/src/modules/class- woocommerce-hpos-orders.php on line 204** * I use the Astra theme and have tried using a standard theme for troubleshooting but the issue persists. Also, I do not have Jetpack installed, but the URL mentions that plugin. There also seems to be a typo in the URL (“automattic”); could this be causing the issue? * Please find the screenshot below: * ![](https://i0.wp.com/www.lisa-spricht.com/wp-content/uploads/2024/04/Screenshot- 2024-04-10-at-12.41.29.png?ssl=1) * Your help would be greatly appreciated. * Thank you, Lisa * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fundefined-array-key-47%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 6 replies - 1 through 6 (of 6 total) * [carolm29 (woo-hc)](https://wordpress.org/support/users/carolm29/) * (@carolm29) * [2 years, 1 month ago](https://wordpress.org/support/topic/undefined-array-key-47/#post-17683070) * Hey there, [@lisaxdfsjh](https://wordpress.org/support/users/lisaxdfsjh/)!

Also, WooPayments has a new version which was recently rolled out, you can install in on a staging site and make a test purchase, I’m confident the issue has been fixed with the most recent update. * As for [@lisaxdfsjh](https://wordpress.org/support/users/lisaxdfsjh/), it’s been long since we last heard back from you. I’ll therefore go ahead and mark this thread as solved. Should you have any further questions or concerns, please feel free to reach out. * All the best!
