header warning in php 5.0.3

[scorpioy]

I got an error like: Warning: Cannot add header information - headers already sent by

I found some solutions from google. The most common reason is: have some blank line/space in the end of config file. But there is no such problem on my config file. In fact, header did not show this error when I run on php version 4. Now I migrate to version 5.0.3. with the same php code. Would this be the reason? How to solve it?

Thanks.

Exact same code?

Could be that PHP changed the way that one of the function's works, and it already outputted something to the output buffer before your header was sent.

Maybe paste some code for us to look at? If someone else knows a quick fix, feel free to step in!
