what am I forgetting: local test version of WP goes to live site

Hi,

Problem: I installed a local version of a live site to test some stuf. But if I try to go to the local site, it autimatically goes to the live site.
I had this problem before, but i thought I now did everything the same way as when I resolved it last time…

I have a live site that I need to make a local test version from.
I edited the wp-config like this

/** MySQL database username */
define('DB_USER', 'root');

/** MySQL database password */
define('DB_PASSWORD', 'root');

and in the database I changed the site url and the home to the local address (http://localhost:8888/localmapname)

What am I missing?? Why is it still going to the live site?
Please help
THANKS!
