I’m wondering if the new site is talking to the old site’s database?

Quick way to figure out is to look at the site settings from the new site’s admin dashboard. If they match the old site’s URL then you know that’s the problem and you can’t fix that from where you are at as ‘Admin’ most likely refreshed when you changed to ‘Settings’ to use the original site’s address so don’t try that. The cookies are the same so the session would have tolerated that change.

Or you can create a new test post from the new sites admin. If it shows up in the original site then you have a problem with using the wrong database or database tables.

Watch the browser bar. That will tell you and of course, the credentials for the new site’s wp-config should be very different in the database section or at least show a second different table prefix.

If you’d done a fresh install you’d have a new database or created the new prefix. Copying everything over didn’t create a new database… but a new database would have required copying the database or it’s content over, too.

Of course the site settings were CLONED from the old site. One text change to include the correct sub-directory and I’m off to the races.

Thank you so much @jnashhawkins !!!
