My web page says "404 File Not Found"
Issue:
When I clicked on a link or typed in the URL to my web page, it gave me an error message that read "404 File Not Found".
Solution:
This occurs because the web browser can not find the file you're looking for with the URL that you supplied it. The link you clicked was broken or outdated or you typed in a wrong or old address, or the file has been moved or deleted.
To resolve the issue, check the URL that you use for the file and verify that it is correct. If it is, verify that the file has been uploaded to your web space.
Also, UNIX is case sensitive. To prevent problems, name all your files in lowercase, else a case typo could case the error.
Troubleshooting: Relative URLs vs. Absolute URLs
