The already existing website has been migrated off the host server to work on it locally.
The problem is when viewing the main site, only the Home page or Search Results page will load. Clicking links to any local pages (other than those two) will load the XAMPP default page (http://localhost/xampp/). The link URLs all appear to be correct, they just don't go where they should.
On the other hand, can login and navigate the admin pages without any problems - everything there looks like it's where it should be.
Scratching my head on this one! Setup:
