 is declared:

 `wp-includes/deprecated.php` file.

 present. Why? Since there's an incomplete installation of the duotone
 file, it's probable other files may not have been updated too.

 Thanks for this ... I notice that the manual update documentation says to
 manually erase and replace with new files /wp-admin and /wp-includes -

 If this is still the correct process, then will try this next. Please
 confirm...
