Home Undefined parameter when doing URL RewriteRule
 I have noticed some occasional URL issues in my google crawler errors with a rewrite rule I use to make a clean URL. Any help is greatly appreciated. Here is what I am occasionally seeing as the error: http://www.example.com/store/undefined/undefined/  It should be something like this: http://www.example.com/store/1234/store-name/  Here is my htaccess rules:  RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(\w+)/([\w-]+)/$index.php?id=$1&ch=\$2 [L]
