Now I have two domains for my WordPress, running in Network mode.
I've added it as alias in my dns setting (it's not the problem).
When I open my second domen, WP says "there's no such site seconddomen.firstdomen.com".
The only thing I need is to open main page with my second domen. Links can point to the first domen
I've installed this plugin, but I cannot add a domain for site with ID=1 (main site), thought other IDs are working!
How can I solve that problem? (without using any plugin that can be more useful!)
