Troubleshoot 404 error pages

Problem

All of my pages are generating 404 error pages.

Cause

URL redirection is most likely not working.

Resolution

All installations ship with a .htaccess file to facilitate "pretty URLs". Please ensure that you are using redirect rules appropriate for your web server.

If you're using Apache web server and your .htaccess file is not working please ensure:

1. mod_rewrite is enabled
2. "AllowOverride" is not blocking .htaccess usage
