advance gb 2.3.1 template problems

hello! i am having some confusing problems with my freshly installed gb (haha! yep, my previous one got hacked through that sql injection thing).

first off, i have these lines on the top of my admin page upon logging in:

although things were still normal. i could edit style. i could do easy admin. but then this is what i get when i try to edit my templates:

Warning: Cannot modify header information - headers already sent by (output started at /home/chinito/public_html/guestbook/admin/config.inc.php:83) in /home/chinito/public_html/guestbook/lib/admin.class.php on line 33

my template doesn't change no matter how many times i submit the new settings. it always reverts to the default.
