Problem: The client reported a crash on Greek product pages when using the Klarna for WooCommerce plugin, despite it working correctly in other languages. The error logs indicated a fatal error due to a null object reference in the Klarna plugin, suggesting a conflict with WPML's handling of translated products and WooCommerce Blocks.
Solution: We initially attempted to resolve the issue by applying a temporary code snippet to check for null product objects on the Greek product pages. However, this did not fully resolve the issue. The client managed to fix the display of the Greek product pages by correcting the template used, but the Klarna plugin still caused crashes when enabled. We recommended creating a staging site to further investigate the issue without affecting the live site.
If this solution does not apply to your case, or if it seems outdated, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. If the problem persists, we highly recommend opening a new support ticket at WPML support forum.
