Not sure what happened. * Forum: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) In reply to: [Try to update setting and get this error](https://wordpress.org/support/topic/try-to-update-setting-and-get-this-error/) * Thread Starter [roenator](https://wordpress.org/support/users/roenator/) * (@roenator) * [13 years, 8 months ago](https://wordpress.org/support/topic/try-to-update-setting-and-get-this-error/#post-3031403) * But I didn’t actually get logged out. All I did was add `add_theme_support( ' post-thumbnails' );` to the functions.php file in my theme. Even if I take the code away I still get the errors. I don’t know what’s happening but it surely isn’t a good thing. * Forum: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) In reply to: [Try to update setting and get this error](https://wordpress.org/support/topic/try-to-update-setting-and-get-this-error/) * Thread Starter [roenator](https://wordpress.org/support/users/roenator/) * (@roenator) * [13 years, 8 months ago](https://wordpress.org/support/topic/try-to-update-setting-and-get-this-error/#post-3031402) * I logged out and got this mess of errors: * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-login.php on line 362 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-login.php on line 374 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 697 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 698 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 699 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 700 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 701 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 702 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 705 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 706 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 707 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 708 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 711 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 712 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 713 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 714 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/09/4264109/html/wordpress_2/wp-content/themes/custom2/functions. php:15) in /home/content/09/4264109/html/wordpress_2/wp-includes/pluggable.php on line 881 Viewing 3 replies - 1 through 3 (of 3 total)
