I just upgraded from 2.2.3 to 2.3 and every looks fine except for one small problem. I set up a subdomain to get to my blog where blog.nysrpa.org points to http://www.nysrpa.org/blog. This worked fine before the upgrade. Now it fails sending you back to http://www.nysrpa.org. I tried changing to the default theme to see if that fixed things. It didn't. I deactivated all the plugins and that didn't help either. Thoughts?
