Complete error:

Warning (2): Cannot modify header information - headers already sent by (output started at /Applications/XAMPP/xamppfiles/htdocs/trunk/dafe/cake/basics.php:355) [CORE/cake/libs/controller/controller.php, line 743]

As far as I can tell it happens after I try to redirect. I know it’s caused by a whitespace but I can’t find it anywhere, where does this error tend to be?

EDIT: Forgot to mention, this problem only happens on my Mac, my partner working on windows does not have this issue, redirection works appropriately for him.

    Two possibilities I know of:
    A. You might have some whitespace after the class closing PHP tag ?>.

    B. You are trying to echo/ pr() during the processing of the data/ logic (-while it’s redirecting, saving to the database, etc)
