Problem: The client's content managers, responsible for translations, lost access to posts and pages after an update, receiving a message stating they do not have the rights to translate from NL to ES. Solution: We recommend updating to the latest version of WPML, as this issue should be resolved in version 4.6.9. Before updating, ensure to have a complete backup of your site. For more information, please refer to our errata page: WPML custom role based on the editor role cannot edit translations and behave as editor.
