I have wordpress up and running as well as gallery 2. Wordpress is on the root domain, and gallery on a subdomain. Individually they both work great!
Wordpress as a plugin called Ultimate Gallery2, which lets wordpress display random images from your Gallery site on the front page.
While trying to set it up, I can connect to the db just fine, but it says the URL is in correct, although it IS correct. I am entering: http://gallery.domain.com (which works when I browse to it).
I'm wondering if anyone knows what the problem might be? I'm thinking maybe it doesn't support subdomains?
