update:
you know guys, now i know why Poland is so good in consumer IT products and solutions – the forums are often much more helpful ??
if you are having problem with headers in line 1 like this one:
“Warning: Cannot modify header information – headers already sent by (output started at /mnt/web1/[path]/wp-config.php:1) in /mnt/web1/[path]/wp-login.php on line 255
and you do not see any whitespaces in your file in the first line, it means that Unicode Signature BOK is included (which i guess MS notepad automatically ads).
Open file in Dreamweaver,jEdit or any other you know it can remove the signature, fin page properties ( or relevant function ) and remove the BOK.
Upload and heading error will dissapear.
