Hello, I please need your support. So, I recreated a new Google API key, reinstalled translatepress plugins. however, I still get the message: there was an error in your google translate key?? Thank you.
No, everything is saved in your database and won't be lost at deactivation/reactivation. You can remove all the translations by following the steps here: translatepress.com/docs/developers/delete-all-translations-and-plugin-data/
The free version is still available for download here: wordpress.org/plugins/translatepress-multilingual/. The video above is covering the pro version but you can still use TranslatePress for free, just like before.
