cant log into my admin panel

when I try to login to my admin panel, I get this error:

Warning: Header may not contain more than a single header, new line detected. in /home/gosoldie/public_html/countryal/wp-login.php on line 279

Warning: Cannot modify header information – headers already sent by (output started at /home/gosoldie/public_html/countryal/wp-login.php:279) in /home/gosoldie/public_html/countryal/wp-login.php on line 281

when I try to reset my password I get:

Warning: Header may not contain more than a single header, new line detected. in /home/gosoldie/public_html/countryal/wp-login.php on line 279

Warning: Cannot modify header information – headers already sent by (output started at /home/gosoldie/public_html/countryal/wp-login.php:279) in /home/gosoldie/public_html/countryal/wp-login.php on line 281

I’m about to reinstall WP but would like to avoid that if I can. Any ideas?

Thanks
