   Ok, so I've looked everywhere I can think of for a solution, and I've been through this:

   http://codex.wordpress.org/Answers-Troubleshooting#Headers_already_sent

   Countless times but it doesn't help.

   The problem I'm getting is lots of version of this, whatever I try and do.

   <b>Warning</b>: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\wordpress\wp-content\themes\clinical\functions.php:1) in <b>C:\xampp\htdocs\wordpress\wp-content\plugins\twitter-tools\twitter-tools.php</b> on line <b>1106</b><br />

   Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\wordpress\wp-content\themes\clinical\functions.php:1) in C:\xampp\htdocs\wordpress\wp-includes\classes.php on line 1586

   Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\wordpress\wp-content\themes\clinical\functions.php:1) in C:\xampp\htdocs\wordpress\wp-includes\pluggable.php on line 865

   So I've followed the solution as detailed in the FAQ but it doesn't help, there are no extra characters at the start or end of my functions.php file.

   Any help will be greatly appreciated.

   Remove twitter tools, then see if the problem exists..

   I deleted three unused plugins, no change, it was never specifically to do with Twitter Tools, the error occurs when I add new posts, when I click the 'more' tag on the post creator, when I post comments. Virtually any action causes it.

   Disable all plugins, and switch to the default theme..

   If your installation then functions you know it's one of two things, either a plugin or the theme, then start enabling one thing at a time until the problem is re-produced..

   Also check your config file (wp-config.php) and make sure there's no extra spaces on the end, after the ending ?>

   I should have probably added that I'm new to wordpress and attempting to build a theme.

   Its definitely the theme that is at fault. With other themes active it's fine, and when I empty the functions.php file its fine.

   I've tried replacing the functions.php file with one from the classic and the default theme and it still doesn't work :/.

   Perhaps I'm writing a functions.php file wrongly? I can't seem to find any guides as to how they should be written though.

   Oh and I checked the wp-config file and there isn't an ending ?> I unzipped the 2.8.2 WordPress download and the sample doesn't have an end tag either.

   It tells you the error

   C:\xampp\htdocs\wordpress\wp-content\themes\clinical\functions.php:1

   There's probably a blank line at the start of that file. Which editor are you looking at it in?

   There's not meant to be a closing ?> at the end of wp-config.

   Its definitely the theme that is at fault.

   just like described in the faq :)

   DONT use a plain text editor, dont introduce spaces or other 'stuff' before the opening <?php

   thats precisely what that error suggests is happening.

   I'm using Notepad++, I may be new to Wordpress but not XHTML/CSS etc.

   With the show all characters option selected in Notepad++

   http://www.ispycreativity.com/uploads/wordpress-errors/wordpress-functions-php-show-all-chars.jpg

   The below images should (hopefully demonstrate that there are no extra characters.

   and the functions.php file, saved as phps (I've never used this format before).

   If someone manages to resolve this for me I'll be eternally indebted to them.

    Hmm, when the functions.php file is completely empty no errors occur, however when I add just

    <?php ?>

    the error occurs.

    I've just started a new theme and I'm still getting the same error even though I swear to god I'm doing it perfectly.

    I'm using the latest wordpress version on a local xampp install.

    The error I'm getting is:

    Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\wordpress\wp-content\themes\naturally-dark\functions.php:1) in C:\xampp\htdocs\wordpress\wp-includes\pluggable.php on line 865

    Could it be something to do with the fact it says C:\xampp\htdocs\ as opposed to http://localhost/?

    2 months later I finally found the solution. Thanks to: http://stackoverflow.com/questions/1067742/clean-source-code-files-of-invisible-characters

    The character was a Byte Order Mark "a Microsoft invention to tell, in a Unicode file, in which order multi-byte characters are stored.

    To get rid of it, tell your editor to save the file either as ANSI/ISO-8859 or as Unicode without BOM".

    To do this in Notepad++ go Format > Convert to UTF-8 without BOM then Format > Encode in UTF-8 without BOM.
