Child Theme functions.php breaks redirect

    After updating my site to 4.2.3 I get an Error on redirects and the media section doesn’t load. So I can’t login or see a preview of a page.
    When an Error shows up it is:

    Warning: Cannot modify header information – headers already sent by (output started at /htdocs/wordpress/wp-content/themes/formation_child/functions.php:1) in /htdocs/wordpress/wp-includes/pluggable.php on line 1196

    I tried to delete every thing in the Child-Theme folder except a minimal version of functions.php and the style.css, but I still get the Error. I also try to deactivate all Plugins with no success. When I delete the funcitons.php, I have no problems, except that the style from the original theme wasn’t loaded. So the error depends on the functions.php.

    My current functions.php looks like:

    <?php
function theme_enqueue_styles(){
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );

    Its the same as in this Post: https://ww.wp.xz.cn/support/topic/child-theme-functionsphp-breaks-admin but there is no answer.

    I tried it with a closing PHP-tag an I search many times for Spaces. My encoding in the child-theme is UTF-8.

    Thanks for any help.

    According to the error report, your child theme directory is formation_child and not formation-child.. I think they work the same but, it should be a dash one, as per the codex.

    Also, try erasing multiple line breaks in PHP files, you could also use 

    ob_start();
// do the redirect
ob_end_flush();

    To avoid such errors. Just saying!

    renaming was the trick. It’s working again. I don’t know if this solved the problem or if there was an other error from the update which would be solved by a new template.
    So I have to reenter the template settings, but it’s working!
    So thank you very much!

    No worries, the error just faded away as you have set up the child theme properly.

    Glad this has fixed you issue. You’re welcome, and have a nice day !!
