I have a WordPress site that's set up as an add-on domain to my main site. It has its own URL and when you visit the WordPress home page it displays that URL accurately, like "wp_site.com". Visiting any pages within the WordPress site however shows my main site, then the WordPress site in the URL: "www.mainsite.com/wp_site.com/contact" for example. Then if I use the "go to previous page" arrow even the WordPress homepage shows "www.mainsite.com/wp_site.com". The main site is supposed to be anonymous.
I tried resetting the site address, directing it specifically to the add-on domain address and it came up as "not found" and crashed, requiring me to reinstall WordPress.
Is there a way to either substitute the URL that displays, or simply not show one?
