 If you are using Apache, and due to new friendly URL features added in 1.10, you will be required to <b>AllowOverride All</b> (and possibly install the ModRewrite extension for Apache). This means that, inside your Apache configuration (or your VirtualHost configuration), you will need to have a block similar to this (the directory given is the same as in the <i>DocumentRoot</i> directive):

 Once you've made sure "AllowOverride" says "All", you can safely save the file, get out of it and reload the web server (<i>sudo service apache2 reload</i> under Debian/Ubuntu, or click right on the WAMP/XAMP/EasyPHP icon and "reload web server" under Windows).
