My b2evolution Version: Not Entered

Hi --

I just messed everything up with my blog trying to get the automatic picture posting through Flickr.com to work. Yes, I read all the previous posts regarding this but never got it to work AND ended messing things up for my blog as well.

Now, when you goto my blog, you see these warning lines at the top above the header image:

Warning: Cannot modify header information - headers already sent by (output started at /home/listera/public_html/blog/conf/_advanced.php:1159) in /home/listera/public_html/blog/inc/MODEL/sessions/_session.class.php on line 222

Also, when I try to log onto the Admin area, I cannot get in and THIS is the list of warnings I get:

WTF. I edited one spot in the /conf/_advanced.php as instructed in one of the previous "flickr to b2evolution" posts. The edit didn't work so I changed it back. I made the edit by downloading that file via FTP, making the change in Dreamweaver then uploading it back up replacing the old file.

I don't know what I did but I didn't think I did THAT much. Can anybody help me get it back the way it was? I promise to leave the Flickr shit alone after that.
