can’t login after site transfer…

Hello,

I recently moved my site from one host to another. Everything
works fine but when I try to login I get the following error:

Warning: Cannot modify header information – headers already sent by (output started at /home/dean777/public_html/stompersoccer.com/blog/wp-config.php:57) in /home/dean777/public_html/stompersoccer.com/blog/wp-login.php on line 202

Anyone know what I can do to fix this?
