Modifying fields with SQL request in wp_posts table

Hello,

I want to modify the content of standard fields in my forms (for example the “message sent” message). So I executed a ‘find and replace’ SQL request on wordpress posts having the post_type ‘wpcf7_contact_form’.

It changes my ‘wp_posts’ table accordingly but it has no effect on contact forms in the wordpress admin panel or on the website.

Do you have any clue why?

Thanks a lot,

Nicolas
