This package installs the following sites:
The steps to install each site depend on where it is being installed:
Installation on a privately hosted site requires extra steps which should not be needed on siteground, in the following instructions ones that should not be needed if installing on siteground are in italics
It would probably be simplest to create a distinct subdomain for each site, except that the install instructions would be more complex.
I did hit some issues getting internal links to work on backup.act.stringerhj.co.uk the key issue being that nginx doesn't use .htaccess files written by wordpress and so needs equivalent nginx rules. The key issue being that it knows where to find the index.php file for each site.
Siteground is designed to work with wordpress and so does obey .htaccess rules. Examination of the .htaccess files on siteground for oldsite and the main directory suggest that it has suitable configuration. The fact that both oldsite and the main site work strongly suggest that 3 sites in a domain/subdomain will work.
Now you should be able to install wordpress by following the links in this section.
Each wordpress install will require you to enter a database name, user name and password. You should have done this in the previous steps and noted the relevant values
This will take you to the CC wordpress site, rather than the html home page which contains links to the original site and so gets redirected
Test - In the dashboard test that everything you expect appears and that pages and posts can be edited
Expected result - Everything is present and pages and posts can be edited
Test - View the site and try navigating to a post or normal page to view it
Expected result - Pages and posts should be viewable
Errors and corrective action - It is possibe that permalinks need resetting, you can do this in the dashboard by visiting Settings -> Permalinks and saving the page. This will rewrite the rules in the .htaccess file. stringerhj.co.uk uses pure nginx which needs rules setting manually in the server block. Hopefully this won't be necessary on siteground.
The following issues will need fixing to make these backups into fully working sites:
