Problem: You are encountering a fatal error when trying to add a new post, page, or WooCommerce product in WordPress. The error message indicates a TypeError involving WPML and WP_Post. Solution: First, ensure you are using the latest version of WPML. You can check for the latest version under My Account -> Downloads on the WPML site. If updates are not visible, you may need to click the 'Check for updates' button in the Plugins → Add New Plugin → Commercial tab. Before updating, we recommend backing up your database. If the issue persists even after updating, try disabling all other plugins except WPML to see if the problem still occurs. This can help determine if there is a conflict with another plugin.
If these steps do not resolve the issue, or if the solution provided here becomes outdated, please visit related known issues and confirm that you have installed the latest versions of themes and plugins. If the problem continues, we highly recommend opening a new support ticket for further assistance.
