htaccess mod_rewrite problems, what's wrong with my file?

Question

What's wrong with my .htaccess file?

RewriteEngine on
RewriteRule ^/([a-zA-Z]+)/([0-9]+)$ index.php?mode=$1&id=$2 [L]

Basically I want it to go from example.com/?mode=page&id=1 to example.com/page/1

From what I see,it's supposed to work but it doesn't...

Answer 1

1. Remove leading / from your rule
2. Add RewriteBase / after RewriteEngine line
