Trouble with Session

[Shame]

So I am getting this error:

Warning:  session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/rpg/public_html/header.php:2) in /home/rpg/public_html/header.php on line 68

And I don't know how to fix it? Any insight?

[danger boy]

Post the code :)

I would appreciate it if some one could help me out. And I am willing to pay by the hour if some one has a AWESOME reputation around this forum for being able to program well. I just need to figure out what I did wrong. I must say that I did not code this myself, and that I did heavily modify it. And I must have made a mistake, obviously, and I need to get it fixed so I can launch my site in February like I plan.

[Magictallguy]

In functions.php, does it have session_start(); in there already?

If so, simply remove it from the code you've posted here

[Zeggy]

It means you've already sent output before starting the session. Looking at your code, the error's probably in functions.php.

Check if you're echo/printing anything, if you've already started a session, if there anything before the PHP opening tag or after, etc. Even whitespace.

[Shame]

I don't mean to offend any one, but you're all wrong.

It was a simple fix and what I did was comment out the start_session();

and it was done.

I do appreciate you all trying to help. Thanks.

 

FreeRpgSpot is my other account. In hopes I could promote it in the future.

Woops, I do apologize. MagicTallGuy was the closest person to having the correct answer.

Appreciate it again guys. And sorry for the double post.

[Zeggy]

We were both correct. You found a solution, but you still don't understand what the problem was.

The problem is quite clear in the error message: "headers already sent (output started..)".

From the way you fixed it, that means you already started a session and was trying to start another one, which we both said. We just couldn't give a more specific solution because we didn't have all the code to view, we only had your error message to work with. :)
