Even after removing a language from WPML’s options on your website, you may continue to see your theme and plugins downloading language files in that language. To fix this, you need to delete all of the MO and PO files for the language you removed from your site.
To do this, follow these steps:
- Access your website using an FTP Tool such as FileZilla.
- Go to your site’s ../wp-content/languages/plugins/ folder.
- Delete the MO and PO files ending with the language code of the language you want to delete. For example, if you removed the Spanish language (ES) with the Spanish locale (es), the language files would end with -es_ES.mo and -es_ES.po.
- To delete theme translations, open the themes folder in ../wp-content/languages/ and follow the instructions from the previous step.
