I installed WordPress in the root of my web site. Everything went well.

But now, other scripts and files, totally unrelated to WordPress, in other folders, cause WordPress 404 errors. For instance, I copied Docuwiki to a folder called example.com/docuwiki and when I try to run the install.php file from there, I get a 404 error.

Is there any way to work around this, other than moving Wordpress to a different directory?
