How to deny access to a particular wordpress site url

Question

You can prevent access to the file in question by modifying your .htaccess file or creating one, should you have none, with content as follow:

# BEGIN Prevent access to README
<Files "README">
    order allow, deny
    deny from all
</Files>
# END Prevent access to README

Please note: your .htaccess file should be located in the same directory as the file in question; either: in your error folder.
