# 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](New+Installation#WebServer) 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](https://httpd.apache.org/docs/2.4/mod/core.html#allowoverride)" is not blocking `.htaccess` usage
