Login Error

I was trying to login into my admin with https://mydomainname.com/wp-login.php and got the error below:

WordPress database error: []
SELECT user_id, meta_key, meta_value FROM wf_usermeta WHERE user_id IN (2) ORDER BY umeta_id ASC

Warning: Cannot modify header information – headers already sent by (output started at /home/wforoedl/public_html/wp-includes/wp-db.php:1355) in /home/wforoedl/public_html/wp-includes/pluggable.php on line 1228

Will appreciate a hand to help sort it out.

Thanks for your anticipated response.

Regards
