errors in instalation

Hello guys

This is the first time im creating a wordpress website . I have used other softwares but never wordpress even if i like this software so much.

Lets start . I have succesfully uploaded everything in ftp and made changes to config.php

I went here wp_admin/install.php and installed it succesfully .

When i go to login i see strange errors like this :

Warning: Cannot modify header information – headers already sent by (output started at /home/alban/public_html/elektronika-al.info/wp-config.php:1) in /home/alban/public_html/elektronika-al.info/wp-login.php on line 302
