This entry will be brief.
Sometimes we must change the administration e-mail of a web, that one that we find in Settings -> General, but as it shows us, it will not change until it is verified in the previous mail.

This is all very well for security reasons, but what happens if we do not have access to the previous email?, we have to change it in the database.
And this is where you will find a lot of tutorials on the web that will tell you to change the admin_email
field in the wp_options
table in the database.
But it turns out that if you actually do that, you will end up with the same confirmation screen and, therefore, the same previous problem:

And you will have to change it both in admin_email
and new_admin_email
of the table wp_options
(remember to change the prefix wp_
by the corresponding prefix of your WordPress installation).
You can display both fields with this query:
SELECT * FROM wp_options WHERE option_name LIKE '%admin_email%';
And there change both emails.

Short, isn’t it?
