WP SET UP PROBLEM

You say you changed the Site Address (url) to https://www.stuttonplaygroup.org.uk but what have you set the WordPress address (URL) to?

WordPress address (URL) should be set to where your wordpress installation resides e.g. if you have installed in the root of your domain it would be https://www.stuttonplaygroup.org.uk, or if you have installed it in a seperate directory (say /wordpress) then it would be https://www.stuttonplaygroup.org.uk/wordpress

Note you can also set these values in wp-config.php which overrides the values set through the adimin page:

define(‘WP_SITEURL’, ‘https://www.example.com/wordpress’);
define(‘WP_HOME’, ‘https://www.example.com’);

or

define(‘WP_SITEURL’, ‘https://’ . $_SERVER[‘SERVER_NAME’]. ‘/wordpress’);
define(‘WP_HOME’, ‘https://’ . $_SERVER[‘SERVER_NAME’]);

It is just in the root.

When I initially set the site up I set the –
WordPress address (URL) to: https://www.stuttonplaygroup.users58.donhost.co.uk
Site address (URL) to: https://www.stuttonplaygroup.users58.donhost.co.uk

I then modified the theme and added pages, images and text content. The client said the site was approved.

So, I changed the domain name nameserver information to point at my server space and away from the old website.

I then changed –
WordPress address (URL) to: https://www.stuttonplaygroup.users58.donhost.co.uk
Site address (URL) to: https://www.stuttonplaygroup.org.uk (the correct domain)

Only other change was on my server where I mapped the account to the correct domain: https://www.stuttonplaygroup.org.uk

Have I explained that clearly?

The problem has been fixed. The server people tell me ‘The host headers have now been re-added for this domain’. No idea what that means but thank you for your help!
