I wish I had a quick answer for you, but I don't. You do say it 404s... are you sure it's not a 500 error ? Perhaps I don't fully understand the problem. "links site no longer works and gives the HTTP 404 - File not found error. However, it correctly redirects me from /links to /links/directory/ " ... but I presumed, after it redirected, you got a 404. Does the script work correctly if you browse directly to /links/directory/

The bundled index.php really does nothing except re-direct the browser to the actual script, which is the file named simply "directory" The directives in the included .htacess file tell your web server to treat the
"directory" file as a PHP file, despite having no .php file extension.

For the most part, no script should care if register globals is on or off until a form is submitted,.

Also, according to some of the previous Dew-Code visitors, some servers don't process changes in .htaccess files right away. I recall thinking one guy's server was possessed because changes were not readily apparent. He had to wait up to 15 minutes for changes to .htaccess files to take effect.

I beleive you can PM me the url to your installation by clicking my profile link. Perhaps I could figure something out after seeing how it behaves.
