Driving me nuts: search is broken.
I've deactivated all plugins, set permalinks to default, tried the default theme, checked the search submit form code, upgraded to 2.9.2. There's nothing in functions.php that effects search.
All I get is a chronological list of posts.
Search does work OK in admin when searching posts. WP is installed in /blog, but there's nothing in the root .htaccess except for some 301 redirects, and no index.php, either.
