Headers alrady sent?

I upgraded from 71 to 72, and everything is fine except for when I try to edt a post, I get this error:
SQL/DB Error —
[Unknown column ‘post_lat’ in ‘field list’]
Warning: Cannot modify header information – headers already sent by (output started at /home/kurunin/public_html/blog/b2-include/wp-db.php:96) in /home/kurunin/public_html/blog/wp-admin/b2edit.php on line 298
and yes, I deleted the whitespace at the end of wp-config.php
