Title: “Cannot modify header information” issue Last modified: August 19, 2016 --- # “Cannot modify header information” issue * Resolved [musto](https://wordpress.org/support/users/musto/) * (@musto) * [16 years, 2 months ago](https://wordpress.org/support/topic/cannot-modify-header-information-issue/) * Hi, * I’ve just installed wordpress and edited my wp-config. Install was ok. Now, when I access: [http://www.website.com/wp-login.php](http://www.website.com/wp-login.php) I have the following lines of errors above the login form: * > Warning: Cannot modify header information – headers already sent by (output > started at /home/oza/www/wp-config.php:1) in /home/oza/www/wp-login.php on > line 314 * When I log in as an admin I have blank screen with: * > Warning: Cannot modify header information – headers already sent by (output > started at /home/oza/www/wp-config.php:1) in /home/oza/www/wp-login.php on > line 302 > Warning: Cannot modify header information – headers already sent by (output > started at /home/oza/www/wp-config.php:1) in /home/oza/www/wp-login.php on > line 314 > Warning: Cannot modify header information – headers already sent by (output > started at /home/oza/www/wp-config.php:1) in /home/oza/www/wp-includes/pluggable. > php on line 665 > Warning: Cannot modify header information – headers already sent by (output > started at /home/oza/www/wp-config.php:1) in /home/oza/www/wp-includes/pluggable. > php on line 666 > Warning: Cannot modify header information – headers already sent by (output > started at /home/oza/www/wp-config.php:1) in /home/oza/www/wp-includes/pluggable. > php on line 667 > Warning: Cannot modify header information – headers already sent by (output > started at /home/oza/www/wp-config.php:1) in /home/oza/www/wp-includes/pluggable. > php on line 868 * ` * I’ve Read the FAQ about that. I don’t have any character before or after . As well I created a new wp-config from wp-config-sample and ovverwrittien the existing one a couple of times. I don’t have any quotes missing in wp-config. * Actually, I noticed there is no ?> at the end of my wp-config-sample, is that normal? * It ends with: * > … > /** Sets up WordPress vars and included files. */ require_once(ABSPATH .‘ > wp-settings.php’); * I tried adding ?> but I still have the same issue. * I’ve had a look at all files just after unzipping wordpress-2.9.2.zip, some of them including wp-config-sample don’t and have ?> at the end and some of them appear to have a carriage return character after the ?> * I’ve tried unzipping with winrar and 7zip, same result. * I you have any Idea, it would be much appreciated.
