Problem: After updating WordPress to version 6.7 and ensuring all themes and plugins, including WPML, are up to date, the back office still displays a mix of English and French. Solution: We recommend checking the WPML settings specifically related to theme localization. We found that disabling the option 'Charger automatiquement le fichier .mo du thème à l’aide de 'load_textdomain'' resolved the issue of mixed languages in the back office. You can find this setting under the WPML > Theme Localization section of your WordPress admin.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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. If the problem persists, please open a new support ticket.
