I recently upgraded a site and almost all URLs have changed. I have redirected all of them (or so I hope) but it may be possible that some of them have slipped by me. Is there a way to somehow catch all invalid URLs and send the user to a certain page I am using PHP Thanks so much! error file is already in .htaccess but seems nothing going to change you can see the error file as below

AddHandler application/x-httpd-php5s .php
ErrorDocument 404 /content/404.php
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /

here are 2 different url one the first one is old one which i edited and the secound one is edited one

#1 old one (which is no longer on the server)

http://adsbuz.com/vehicles-cars/toyoya/2009-toyota-land-cruiser-gxr-4686.htm

#2 the editet one which is on the server

http://adsbuz.com/vehicles-cars-for-sale/toyoya/2009-toyota-land-cruiser-gxr-4686.htm

i need only the secound one with the vehicles-cars-for-sale because the other directory is already modified and its not on the server but as you can see after the (adsbuz) site name vehicles-cars and vehicles-cars-for-sale both are opening for same location

I hope I made myself clear
