THANK YOU!!!!!!!
it works

where do i need to put this 2 lines in the wp-config?

i accidently changed the blogurl and the site url in the external server to localhost - thinking it is the local host wp-admin and now all my files in the server are broken - look here: http://www.tween.co.il
and if im tring to go to http://www.tween.co.il/wp-admin - it send me to my local host and dont recognize my password...
do you know how can i change back the site and blog url in my external server to be http://www.tween.co.il?

You can set the urls in your wp-config.php file:

define('WP_HOME', 'http://www.example.com' );
define('WP_SITEURL', 'http://www.example.com');

can i backup my site without the site and blog url?

Hi
I did a backup to my site on the server and i saved the file in my computer
i install a wordpress copy in my root and i copyed all the site from the external server to my root (localhost)
with phpMyAdmin i imported the DB file that i just saved, but i think it came with the site url (the url of my external server) - so i cand login to the admin pannel in my localhost - it send me to the admin on my server and not in my localhost...what can i do?
