Deprecated: wp_richedit_pre is deprecated
I have a WordPress site running version 5.51. When I try and create a new page I get the following error above the editor.
Deprecated: wp_richedit_pre is deprecated since version 4.3.0! Use format_for_editor() instead. in /var/www/html/cwc/wp-includes/functions.php on line 4773
I am using the latest version of WordPress while would I see such a message?
