"Cannot modify header information" warning

[loutfie_mahdi]

I've just started using Mantis BT I have problem when I was checking for error. When I tried to enter the same user account it came with "Cannot modify header information - headers already sent by (output started at D:\mantis-0.19.2\core\error_api.php:101) in D:\mantis-0.19.2\core\gpc_api.php on line 251" warning.

I already tryied to change the output_buffering to allow multiple header in php.ini but It didn't do any good. Even for some value e.g:(output_buffering = 2048 or On) it even jumped to login page instead of error page(stating user already exist).

Does anyone have any solution for this? Or maybe the exact output_buffering value?

creat an .htaccess under mantis repository

with just inside :

PHP_FLAG output_buffering on

it work..

I think that this may be related to two bugs that have been resolved in CVS (#4995 & #5044). You could try updating core/current_user_api.php, core/error_api.php and config_defaults_inc.php to the latest versions in CVS.

I deleted the trailing white space following ?> from config_inc.php and voila!
