Hello, is this plugin has requirement for server environment since I cannot use it now.
The site is just established without installing other plugin.
Website is https://a.cichilun.com/ceswz.html https://f.cichilun.com
It displays 404 error.
The DNS is right and four SLDs, a, b, c and f, are solved at the same time; a.cichilun.com is the main domain name.
Select $_SERVER[“SERVER_NAME”] (default)
Open f.cichilun.com will just skip to the homepage.
Select $_SERVER[“HTTP_HOST”]
Open f.cichilun.com is the complete site of link with 404 error.
