When I moved my site to DreamHost, I somehow got the idea it should be installed on a subdomain (hgchicago.dreamhosters.com) first, then, when it appeared to be working properly, copied over to my main domain (hgchicago.org). So that's what I did.
Now, if one goes to hgchicago.org, the site seems to work. Most of the internal links go to hgchicago.dreamhosters.com, but some go to hgchicago.org. This is troubling but I can eventually fix it.
More seriously, I cannot login to hgchicago.org/wp-admin. That gets redirected to hgchicago.dreamhosters.com/wp-admin.... Somewhere there must be a setting that causes this, but so far I've not found it and I'm hesitant to go mucking randomly around in the WordPress files. I need know where it might be. (I assume it's in WordPress; could it be something DreamHost did?) Suggestions?
