    Can I double check that you created a ‘styles.php’ file inside your Child Theme folder? That’s not the right file. The file you should have created is ‘functions.php’.

    Once you’ve got that functions.php file created, add this bit of code to the bottom of that file:

    
?>

    Hi Andrew

    Thank you so much for replying. I just mixed things up, when writing this entry, and the file was/is of course called functions.php

    I now added the ?>

    However the error message persists

    Hi again

    Actually the message is a new one:

    Warning: Cannot modify header information – headers already sent by (output started at /var/www/svenskdansk.nu/public_html/wp-content/themes/twentyseventeen-child/functions.php:10) in /var/www/svenskdansk.nu/public_html/wp-includes/pluggable.php on line 1219

    changed the script to this:

    <?php
    add_action( ‘wp_enqueue_scripts’, ‘my_theme_enqueue_styles’ );
    function my_theme_enqueue_styles() {
    wp_enqueue_style( ‘parent-style’, get_template_directory_uri() . ‘/style.css’ );

    }
    ?>

    Now my site is not down anymore, at least:)

    I recently had similar issues and found it was a simple/ridiculous fix of making sure there are no spaces or blank lines after the final ?> in functions.php

    I had same case as @caseywp that I got errors and after I removed blank line after final ?> in child theme’s functions.php everything is fine.

    Error in browser:
