I've just loaded some code up to my testing machine, and I get nothing but "cannot modify header" errors.
I don't get these errors on my dev machine at all.
I've gone through my code, and all my the include which I believe is causing the error is one of the first things in the page, so that shouldn't be the issue.
Is there anything else which would cause this error? -

Usualy the message reads like: -
Warning: Cannot modify header information - headers already sent by (output started at C:\server\www\test.php:x) in C:\server\www\test.php on line y
so it includes the 2 line numbers. What was yours?

I think my line numbers make it even more confusing ronald, I get 3 error outputs, lines 202, 202 (yes twice) and 205.
the worst part is, I only have 130 lines of code on this page, and the included page has 250.
the include is from the facebook php client, and I use that all over the place, so I'm sure the error does not exist in there.

Looking through some other posts, I found a message saying that whitespace prior to the opening php tag can cause this error.
Turns out I had two empty lines before the opening <php? tag.
I removed the lines, and the errors are gone.
