We recently came across this pesky problem and found these two articles very helpful.
Don’t save your UTF-8 files with BOM as it creates issues.
=================
http://juicystudio.com/article/utf-byte-order-mark.php
“Headers must be written before any data is sent to the client. Unicode files may include a Byte-Order Mark (BOM) to help distinguish the big endian and little endian byte order. Unfortunately, the BOM isn’t understood by PHP. Upon encountering the BOM, PHP assumes that it is dealing with data, by which time it’s too late to modify headers. Solution? Save the file in UTF-8 encoding without a BOM.”

“If file A or file B has UTF-8 encoding then you will get the error:
Warning: session_start() [function.session-start]: Cannot send session
cache limiter – headers already sent (output started at index.php:1) in
session.php on line 3
Using UTF-8 encoding WITHOUT BOM (Byte Order Mark) seems to fix the
problem.”

Thank you so much for this post. It is unbelievebale how hard it was to find out how to do this. I was googling for quite a bit before I came across your post. I had assumed it may havebeen something in about:config since there was no option in the standard setting but had no idea what the value would be to change.
i hv installed wp on server which is a win xp pc. instalallation s done as per ur instruction and i can open wp on the server machine..my idea is to develope a intranet blog in the office which can be updated and viewed by other computers connected on intranet( local LAN connecting 5 to 6 PCs..but now the problem is i’m unable to open the wp blog login page from other computers and i’m new to this field.. so please give some step by step procedure on how to connect other computers on LAn to server..
