When you get a 404 error, check the URL in your browser. This tells you the path and file name that cannot be found.
Example:
http://yourdomain.com/astro/Astros/help.html
The file must be in public_html/astro/Astros/ and the names are case-sensitive.
For addon domains, the file must be in public_html/addondomain.com/astro/Astros/ and the names are case-sensitive.

When you have a missing image, go to IE and view your website. You will see a box with a red X where the image is missing. Right click on the X and choose Properties. The properties will tell you the path and file name that cannot be found.

http://yourdomain.com/images/banner.PNG
The image file must be in public_html/images/ and the names are case-sensitive.
For addon domains, the image file must be in public_html/addondomain.com/images/ and the names are case-sensitive.
