I spoke too soon. I followed the Edit functions.php steps for site 2. The home page of site 2 changed correctly. But all inner pages did not change. In addition, the home page for site 1 is correct, but all other pages go to the same incorrect pages that site 2 are now going to.
I might not have explain my issue correctly. Here is what I have going on.
1. I created examplesite1.com with IDStore WordPress theme. Create inner pages and all categories and pages for the eCommerce site.
2. Now I want to take that exact site and copy it over to a different domain name examplesite2.com.
I still want to keep examplesite1.com as is. But I want examplesite2.com and all inner pages to link to examplesite2.com, not examplesite1.com.
Any help would be much appreciated.
