I have an htl protected by .htaccess password. Ita was working fine, but I added other names to the .htaccess and began to have this error
"The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script.
If you think this is a server error, please contact the webmaster.
Error 500"

I went back to the original .htaccess, but still have the same error. The .htaccess file is:

<FilesMatch new.html>
AuthName "Secure Area"
AuthType Basic
AuthUserFile ../htdocs/.htpasswd
require valid-user

What could be the problem?
