Problem: The client is experiencing an issue with WooCommerce Multilingual (WCML) where a warning notification for compatibility of the WCML plugin persists, despite the plugin being updated to version 5.3.5. The notification suggests that 'WCML 5.2.1 and below requires compatibility mode to work', and an 'enable compatibility mode' button appears, which is unnecessary for the updated version and is already enabled.
Solution: We recommend taking a full backup of the site and database, then deleting the option 'wpml_notices' from the 'wp_options' table in the database. After deleting this option, the notice should be removed. If the option reappears and the notice message is still present, we advise contacting the hosting support for further assistance.
Please note that this solution might be irrelevant if it's outdated or not applicable to your case. If the issue persists, we highly recommend checking related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If necessary, please open a new support ticket for personalized assistance.
