What's on and around line 2? Chances are that you are either trying to set a cookie or use header(); _after_ text has already been sent to the browser (thus headers already sent).

It could be as simple as just relocating the problem to the top of the script or using ob to capture any text that would otherwise be output and then set the contents to a variable and then show it after anything dealing with the headers have finished.

Yes, as xPlozion said, that message means that something was sent to the browser before your line 2. The headers must be sent before anything else is sent to the browser.

Maybe we can help if you post your first 2 lines of code.

to this:
Code: 
<?php

Short tags could be the problem, but only if the server doesn't support them. But then again, if they weren't enabled, then the PHP wouldn't execute.

Is there any real purpose for the Cache-Control? You mentioned something about a header.php file. Seeing as how English isn't your native tongue, I couldn't make out your message clearly. Was the header.php file on line 2 or if not, then what line was it on?

I think it would have to be the short tags because the headers are sent on line 1.

And make sure to check that you don't have any spaces on the first line where the PHP tag is, as that will cause the error iirc ;)

But try replacing <? with <?php . There's several reasons to do so: <? is also short-hand for XML, <? is being removed or disabled in future PHP versions 6.* iirc, and it's just plain lazy and frowned upon by the PHP community.
