I have set-up an .htaccess file (listed below) for a newly designed website (the domain has been up for years). One of the errors I am receiving is when a visitor goes to the URL http://example.com/Newsletters/5765-2005.pdf they should be directed to http://example.com/newsletters/5765-2005.pdf (small "n" in "newsletters"). But they somehow are redirected to http://example.com/articles/letters/5765-2005.pdf

The sub-directory "letters" does not exist, nor is it listed in the .htaccess file, unless it is shortening the "newsletters" directory and placing the "articles" directory in front of it.

I have tried the page at http://web-sniffer.net/ and it says it's a 301 permanent move and gives the correct directory where it has moved, i.e., http://example.com/newsletters/5765-2005.pdf

Any one have any ideas of what is going on?
