97 results for a search on “Cannot modify header information”. Probably white space before or after php tags.

Nice Response Rick.  I was trying to figure out how to put that in nice language.  I was going to post this in the lounge…remember that post that usmc wrote some time ago…?

run php_info() on both and see how you have your error reporting set.  Maybe error_reporting is set differently in each environment?

I had exactly the same Problem as TS (Berserk). I did run Localhost on a Windows computer where as my hostingprovider uses Linux. The problem only accured - but not always - with files that were coded in UTF-8 encoding. I used PSPad 4.1 for that task. My solution? I installed the latest version of Notepad++ and saved the files causing error-messages again in UTF-8 format without BOM. Visibly nothing has changed but the error-messages are gone. I hope this will do the trick for you aswell.
