Title: Internal server error Last modified: December 19, 2022 --- # Internal server error * Resolved [dieringelei](https://wordpress.org/support/users/dieringelei/) * (@dieringelei) * [3 years, 5 months ago](https://wordpress.org/support/topic/internal-server-error-699/) * Hello, * my plugin version is 2.12.2. * I tried to test the checkout with Klarna, but I get an error message alternating between “checkout error” and “internal server error”. * I have connected the API successfully and am using the Klarna Payments plugin alongside the Klarna Order Management plugin (which I deactivated during my search for the error, to no effect). * There is this error in the log I activated for Klarna Payments: * ```wp-block-code 12-19-2022 @ 17:54:21 - "Frontend JS 19b125cd-8ee3-957a-b9c8-4bf9c106124a: Successfully placed order. Starting authorization with Klarna" 12-19-2022 @ 17:54:21 - "Frontend JS 19b125cd-8ee3-957a-b9c8-4bf9c106124a: Checkout error | TypeError: klarna_payments.addresses is undefined" ``` * There are also several errors of the same type in the Woocommerce status report, which seem to be connected to the issue. One example: * ```wp-block-code 2022-11-02 18:15:02: KP Create Session Response code: 401 Response message: {"headers":[],"body":"401 Authorization Required<\/title><\/head><body><center><h1>401 Authorization Required<\/h1><\/center><\/body><\/html>","response":{"code":401,"message":"Unauthorized"},"cookies":[],"filename":null,"http_response":{"data":null,"headers":null,"status":null}} Correlation ID: ``` * WooCommerce and the Klarna Plugins are both up to date. Any hint or help is highly appreciated! * Thanks and kind regards * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Finternal-server-error-699%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 1 replies (of 1 total) * [krokedilmartin](https://wordpress.org/support/users/krokedilmartin/) * (@krokedilmartin) * [3 years, 5 months ago](https://wordpress.org/support/topic/internal-server-error-699/#post-16306403) * Hello [@dieringelei](https://wordpress.org/support/users/dieringelei/) Please share the whole system report from your store using a service like [https://pastebin.com/](https://pastebin.com/) Viewing 1 replies (of 1 total) The topic ‘Internal server error’ is closed to new replies. * ![](https://ps.w.org/klarna-payments-for-woocommerce/assets/icon-256x256.png? rev=3174333) * [Klarna for WooCommerce](https://wordpress.org/plugins/klarna-payments-for-woocommerce/) * [Frequently Asked Questions](https://wordpress.org/plugins/klarna-payments-for-woocommerce/#faq) * [Support Threads](https://wordpress.org/support/plugin/klarna-payments-for-woocommerce/) * [Active Topics](https://wordpress.org/support/plugin/klarna-payments-for-woocommerce/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/klarna-payments-for-woocommerce/unresolved/) * [Reviews](https://wordpress.org/support/plugin/klarna-payments-for-woocommerce/reviews/) ## Tags * ["internal server error"](https://wordpress.org/support/topic-tag/internal-server-error/) * [checkout](https://wordpress.org/support/topic-tag/checkout/) * 1 reply * 2 participants * Last reply from: [krokedilmartin](https://wordpress.org/support/users/krokedilmartin/) * Last activity: [3 years, 5 months ago](https://wordpress.org/support/topic/internal-server-error-699/#post-16306403) * Status: resolved
