Problem: You are experiencing an issue where the Admin Language Switcher (flags) has disappeared from the WooCommerce Product Attributes page. This problem occurs despite trying different themes and is specific to the Product Attributes screen, as the switcher works correctly on Posts, Pages, and Product Categories. Solution: We recommend translating the Attributes through the correct section in WPML. You should navigate to WPML > Taxonomy Translation to translate both the Attribute name and the attribute terms. For detailed guidance on translating WooCommerce elements, please refer to our documentation: How to Translate WooCommerce.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your specific case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Should you need further assistance, please do not hesitate to open a new support ticket at WPML support forum.
