Resolved
Reported for: WPML Multilingual CMS 4.3.16
Resolved in: 4.3.18
Overview of the issue
Last WordPress 5.5 version introduced some jQuery updates. This is making that when you try to set A different domain per language at WPML -> Languages -> Language URL format, it doesn’t display the fields for adding your domain names, thus you can’t finish your setup.
Furthermore, you won’t be able to select and add a new WPML Language switcher.
Workaround
We have released WPML 4.3.18 version that should solve this situation. You’ll find more information about it here:
Keep in mind that WordPress core team also released a plugin which may help you handling this situation as it may affect other plugins or themes:
Не помогло ничего!!! Ни обновление WPML 4.3.18, ни плагин Enable jQuery Migrate Helper, ни логаут админки…
Вопрос был решен очень просто: зашел в админку сайта через https://browser.yandex.ru/
И всё получилось! С любовью из Армении! Яндекс крут!
I’m glado to know that it worked! Sometimes it was needed to clear cookies or start a new WordPress session.
Cheers!
