I am runnig WP 3.0.4 multi-site with subfolders. I am running BP 1.2.7 on a secondary blog, blogs.otis.edu/community. If you go to base URL, visitors are redirected that secondary blog.
I can access the site, log in and do stuff. The database seems fine. As long as the URL contains an existing /BLOGNAME, e.g. blogs.otis.edu/otisvrc, the site behaves. 404 Errors will appear for blogs.otis.edu/otisvrc/TYPO.
If the /BLOGNAME doesn't match one of the subfolders, e.g. blogs.otis.edu/summer, it displays the page "Error establishing database connection." instead of a 404 Page Not Found Error.
Any ideas why? Thanks.
