I have 2.3 running in my web root. I also have another, non-wordpress script installed in a subdirectory off that root. The script worked in a prior, non-wordpress version of the site, but now whenever I try to browse to that subdirectory, I get wordress's 404 page. I'm pretty sure the wordpress .htaccess is blocking access to that subdirectory but I don't know why. Other subdirectories (like the one running bbpress) work fine.
Has anyone encountered this problem before?
