Localhost problem

I edit my files at localhost this works fine, but when i push the button store front then the store opens in localhost/storename sofar so good.
But when i push of one of the links in the template at the screen then i jump into the store at the server Gofree.
If i take a look in the system i see the location of the server mentioned but can not delete it.
How to tackle this problem

Did you originally set this up on your localhost or on the web server? Check BOTH of the config.php files (first in the main folder, second in the admin folder) to see if they have the wrong URL
Second thing to change is to go into your admin area, and change the store url under SYSTEM > SETTINGS to the localhost one if it's not correct
