Hey all, rather than have me ramble, it's probably best to cut to the chase and have you see for yourself:
Why is this nonsensical page not redirecting to a 404 error page? I added the proper code to the .htaccess. The homepage is working properly in all circumstances.
Any help would be GREATLY appreciated. I've been looking at this for a week now.
EDIT: If it helps, I ran the header through a validator, and while the home page returns a 404 error when it should, the incorrect URL's in the subpages all return 200 (OK) status.
