host has 2.2 installation program. installed that and things worked fine (this is a new blog). Installation directory was /wordpress/ and when I would go there, could see blog. Then upgraded to 2.6 and when I go to /wordpress/ I am kicked back out to root domain http://www.domainname.com. Same thing when I try /wordpress/index.php . BUT, if I go to /wordpress/?p=1 or wordpress/wp-feed.php , I see blog as it should be. It's almost like a redirect from /wordpress/ to homepage after update to 2.6.
Any hints where to look?
