OK now I didn’t realise that localhost is just the word to insert in the config file. I thought I needed the name of my localhost.

Below is the message I get when I put in https://allhistoryishere.org.uk/wp-admin/install.php
Wasn’t too sure about hostname. I put in allhistoryishere.org.uk since that goes in the hostbox when I use filezilla to upload stuff.

Error establishing a database connection
This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at allhistoryishere.org.uk. This could mean your host’s database server is down.

Are you sure you have the correct username and password?
Are you sure that you have typed the correct hostname?
Are you sure that the database server is running?
If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.

I have an addon site allhistoryishere.org.uk under public_html_wordpress

I put a test index.html file there and it worked. My host is simplexwebs. I then deleted the index.html and uploaded the wordpress package to public_html_wordpress after creating database, user, password and changing the config file. The next stage installation failed. What did I do wrong?
