ACF plugin is causing “cannot modify header information – headers already send by (bla bla bla/public_html/wp-content/themes/bifrost/header.php:1)” in my file.
The firsts 26 lines of my header.php:1 file show:
<!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<meta charset=”<?php bloginfo(‘charset’); ?>”>
<meta name=”viewport” content=”width=device-width, initial-scale=1″>
<meta http-equiv=”X-UA-Compatible” content=”ie=edge”>
<?php
/**
* Queried Object
*
* In case it is shop page get_queried_object won’t
* work, it needs to be changed to a custom WooCommerce
* function wc_get_page_id.
*/
$bifrost_queried_object = class_exists(‘WooCommerce’) && is_shop() ? wc_get_page_id(‘shop’) : get_queried_object();
/**
* Redirect
*/
if (get_field(‘general_redirect’, $bifrost_queried_object) && get_field(‘general_redirect_url’, $bifrost_queried_object)) {
wp_redirect(get_field(‘general_redirect_url’, $bifrost_queried_object));
exit;
}
wp_head();
?>
I already:
1 – checked for blank spaces
2 – moved the <!DOCTYPE html> around
3 – Installed an older version of ACF
4 – and did a lot of other things suggested in previous post, but nothing worked so far.
When I deactivate ACF plugin, my page work fine, but I loose all configuration made using the ACF plugin. Somehow, this same configuration is working fine in bermelloajamil.info, but after migrating this content to bermelloajamil.com, the error shows up. Can you guys help me?
The problem is here
/**
* Redirect
*/
if (get_field(‘general_redirect’, $bifrost_queried_object) && get_field(‘general_redirect_url’, $bifrost_queried_object)) {
wp_redirect(get_field(‘general_redirect_url’, $bifrost_queried_object));
exit;
}
You are attempting to redirect after HTML output has been started. This code needs to happen before
<!DOCTYPE html>
Thanks for your help. I fixed the code as you suggested, but the same error shows:
Warning: Cannot modify header information – headers already sent by (output started at /home/customer/www/bermelloajamil.com/public_html/wp-content/themes/bifrost/header.php:1) in /home/customer/www/bermelloajamil.com/public_html/wp-includes/pluggable.php on line 1421
Here is a snippet of the fixed code:
<?php
if (get_field(‘general_redirect’, $bifrost_queried_object) && get_field(‘general_redirect_url’, $bifrost_queried_object)) {
wp_redirect(get_field(‘general_redirect_url’, $bifrost_queried_object));
exit;
}
?>
<!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<meta charset=”<?php bloginfo(‘charset’); ?>”>
<meta name=”viewport” content=”width=device-width, initial-scale=1″>
<meta http-equiv=”X-UA-Compatible” content=”ie=edge”>
<?php
/**

*
* In case it is shop page get_queried_object won’t
* work, it needs to be changed to a custom WooCommerce

*/
$bifrost_queried_object = class_exists(‘WooCommerce’) && is_shop() ? wc_get_page_id(‘shop’) : get_queried_object();
wp_head();
?>
</head>
Thanks so much for your help!
