I am having header problems around my website, and I need to get this resolved. Here is an example:

 

Warning: Cannot modify header information - headers already sent by (output started at /home/lunarwar/public_html/subheader.php:43) in /home/lunarwar/public_html/maincore.php on line 247

 

Why do I keep getting this. If I want to do things, like CG images, everything gets messed up! Help!

 

Yes, I disabled output buffering so I could see these errors.

 

Here is my subheader.php:
