I was about to finish installing the wordpress files, wrote down .../wp-admin and then the message like that occured:
Warning: Cannot modify header information - headers already sent by (output started at /rswww/wp-config.php:1) in /rswww/wp-includes/pluggable.php on line 881
I tried to get rid of the free spaces in the file what I read could be a reason of the problem. It didn't help, though.
Do you have any clue?
Thank you for your help.
