I want to run wordpress in my virtualbox just for testing purposes. I still want it to be avialable to public, so I'm using a free second level domain for this, which is it.cx. (that's afraid.org service).
So for example I made red.it.cx and blue.it.cx. (not really)
I have dynamic IP, so I installed a service that automatically updates both records.
So I installed wordpress, and it uses red.it.cx for the main site.
Then I enabled sub-domain multi site (actually it was subfolders first, but then I set ('SUBDOMAIN_INSTALL', true)).
How to setup the second site? I dont want another subdomain like blue.red.it.cx, I want another site at blue.it.cx.
I went to add a site, and typed "blue" in the address, so it created "blue.red.it.cx", then changed the URL to "blue.it.cx" from site settings/info tab. The site works fine, but when I try to go to the dashboard, I get some weird redirection. Like:
It doesn't let me login, so I can't manage that blog...
Tried to follow "WordPress MU Domain Mapping" guide, not even being sure if that's what I need, but nothing happens when I click "save" in "Domain Mapping Configuration" or "Domains". I put files as it said, with necessary permissions, and wp-config.php settings.
