The site is not working. Engine problem?

Question

PHP

Help advice. Made a site on word-press. We sent the client an archive with the engine and theme. That is, we just took all the files, including the engine itself and the theme that we created in it. The client simply inserted these files into his hosting. Now he is redirecting to our hosting where we originally installed this engine and the theme in it. We also sent our database to the client.
Maybe the problem is that the client himself had to install the engine and then just download our theme?

Answer 1

The problem is in the site URL settings, wordpress immediately redirects by default.
https://codex.wordpress.org/Changing%20The%20Site%20URL Just let him change the necessary UPD
parameter in his wp-config.php file Well, you can also change it in the database

UPDATE wp_options SET option_value = 'http://mysite.ru' WHERE option_value = 'http://mysite.local';

Answer 2

Go to the VP admin panel on your server
In the settings, change the domain to the customer's domain (the admin panel stops working for you)
Dump the database
Send it to the customer

Answer 3

To transfer the site, you can use the Duplicator plugin .
Create an installation package for yourself and send it to the client.
Then this package will need to be uploaded to the hosting, call the installer.php file and follow all the steps of the wizard. The WordPress settings will update automatically.
