Background of the issue:
I have WPML installed, and so far all is working great. When trying to edit in Gutenberg editor a translated page, WPML gives a notice indicating that it is preferred to use the advanced translation editor. I have dismissed that notice myself with the checked 'do not show again'. But now I want it back.
Symptoms:
The notice recommending the use of the advanced translation editor in Gutenberg editor for translated pages is no longer showing.
Questions:
Is there any key in the DB I have to modify to have this warning shown again to my user profile?
To re-enable the notice again, backup your Website first and go to your server database. Then, locate the wp_options table and delete this field wpml_dismiss_post_edit_te_notice .
Once you've done that, the notice will show up again.
