What is wrong with my short URL rewrite code?

Question

I am trying to rewrite a URL from mysite.com/123 to mysite.com/redirect.php?referral=123

Currently, my .htaccess file is using the code:

RewriteEngine On
RewriteRule ^([a-zA-Z0-9]+)$ redirect.php?referral=$1AddHandler php-files .php

I'm positive it was working before, but now I get a 500 error code.

The last two lines of your file appear to have been concatenated. Change it to:

RewriteEngine On
RewriteRule ^([a-zA-Z0-9]+)$ redirect.php?referral=$1
AddHandler php-files .php
