Dobrý den,

můžete mi poradit jak mám upravit function.php, aby se mi nezobrazoval Warning ? :

Warning: Cannot modify header information – headers already sent by (output started at /data/web/virtuals/266008/virtual/www/wp-content/themes/re/functions.php:244) in /data/web/virtuals/266008/virtual/www/wp-includes/pluggable.php on line 1355
