I need to password protect a directory on my website, and I was trying to use .htpasswd to achieve this. I keep getting an "Internal Server Error" if I try to access that URL from a browser. The server logs don't seem to have a meaningful message (except that 501.shtml and 400.shtml files are not found). Is there anything else that I need to do get this set up? Is there any way to find out what may be causing the internal server error?

Thanks.
