Had a blog in a sub-folder of a site that worked fine. They haven't used it in about 6 months, so I upgraded to 3.3.2 when we accessed it recently. All of a sudden, links go to 404 or homepage - very few go where they're supposed to.
bluewaterpromo.com/blog is the URL of the WordPress part. Most links now don't include the sub-folder /blog/ to make them go to the right place.
Uninstalled, reinstalled a few times (that's why there's no content), deleted databases, checked .htaccess, and changed the blog/homepage URLs several times in settings with no results.
