How to return a domain?

Question

WordPress

The customer in the wp admin changed the current domain to a new domain that is not registered. It doesn't exist in essence. I know it's stupid. Naturally, all access to the admin panel has fallen. Can you please tell me where you need to edit to return the old site address? I was granted access to the host and database

Answer 1

Each hosting makes a daily backup of the database and files, restore it in the control panel. Or, through search replace db, find all lines with a new domain, and prescribe the old one.

Answer 2

Complete the request.

UPDATE wp_options SET option_value = replace(option_value, 'http://domain.ru', 'http://newdomain.ru') WHERE option_name = 'home' OR option_name = 'siteurl';
