| Check your congif.php and function.php files and make sure that there aren't any spaces at the end. For some reason, this screws things up. When I check for them, I put the cursor at the end of the ?> and hold the DEL key for a few seconds, then save, just to make sure I got them all. |

| Okay, just so everyone's aware of this so that there aren't too many more threads about this subject, this is what you need to look for: Warning: Cannot modify header information - headers already sent by (output started at /home/vizzed/public_html/vizzedboard/colors.php :33) in /home/vizzed/public_html/vizzedboard/login.php on line 29 Warning: Cannot modify header information - headers already sent by (output started at /home/vizzed/public_html/vizzedboard/colors.php :33) in /home/vizzed/public_html/vizzedboard/login.php on line 30 Whatever filename appears in the large, red, bold text above is the file you need to check for spaces below the ?> at the end of the file. Again -- 99.9% of the time, this is the file that is reeking havoc on your board, and causing people not to login or out. I should know -- I've experienced this many times.  |

Originally posted by ElricLet me explain the reason: Login.php sends cookies, as we all know. Cookies are made by HTTP Header calls - headers come before content, and if you have any spaces outside the PHP block, that will indeed be send before the PHP is parsed, and thus since the headers have already been sent (content has already been started), you get the error. |

| Another way around this is to use ob_start() before anything else, and ob_end_flush() at the very end of the script (though this generally happens automatically). This turns on output buffering, which catches all echo or print output and waits to send it all at once. However, setcookie() and header() are sent out when they're called, so you can do these things after "outputting" content. |
