Hi michel,
Re-read the bit I suggested above - it's also in the [url="/wiki/FAQ"]FAQ[/url] :

About 99% of the time, headers already sent comes down to one of these things:
o Closing ?> tag with new lines after them. Solution - don't use closing ?> tags
anywhere, ever,*
o Whitespace before a <?php opening tag at the start of one of your files,
o echo (print_r, var_dump, etc) in your non-view files.
* Note that this obviously doesn't apply to views, but rather helpers, libraries, models, controllers and so on.[/quote]
It's one of the more compelling reasons for single-person developers to run a code versioning system - so that you can bisect your way back to a working copy of your project, and identify what change was made that introduced this error
If no data is appearing on screen before the error, it usually means a closing tag somewhere with some blank lines (or even spaces) after it - so check your controllers, models, helpers, and libraries.
Try to identify which pages generate the error, so you can narrow in on where the problem is.
Usual trouble-shooting procedures apply here.
