Fatal error when activating child theme

  • abellerby


    Hi, I have a website using a DIVI theme which I have imported into a WordPress installation on GoDaddy hosting. The site works as expected when using either the Twenty Seventeen theme or Graphene. Twenty Seventeen also works with a child theme but when I activate a Graphene child them I get errors like:

    Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 262144 bytes) in /home/jow0mii4q4m8/public_html/wp-includes/class.wp-styles.php on line 315

    Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 262144 bytes) in /home/jow0mii4q4m8/public_html/wp-includes/class-wp-recovery-mode.php on line 169

    I have tried increasing the memory limit from 256MB to 512MB and instead of the fatal error the website hangs and I eventually get:

    Service Unavailable

    The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

    Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request.

    The admin panel is still available. I have tried disabling/removing all plugins but I still get the same problem.

    Can you help please.

    What are the files in your child theme?



    I have 2 files – style.css which just has the comment at the top and functions.php which has:

    // enqueue styles for child theme
    // @ https://digwp.com/2016/01/include-styles-child-theme/
    function ssas_enqueue_styles() {

    // enqueue parent styles
    // https://codex.wordpress.org/Function_Reference/wp_enqueue_style
    // wp_enqueue_style( $handle, $src, $deps, $ver, $media )
    wp_enqueue_style(‘graphene’, get_template_directory_uri() .’/style.css’);

    // enqueue child styles
    wp_enqueue_style(‘ssasgraphene’, get_stylesheet_directory_uri() .’/style.css’, array(‘graphene’));

    add_action(‘wp_enqueue_scripts’, ‘ssas_enqueue_styles’);

    The same files (with graphene replaced with twentyseventeen) work with the Twenty Seventeen theme.

    Can you obtain and share the error log from the hosting? That would help to pinpoint the issue.



    The error log I have is 400 lines long – how would you like me to share it?

    Thanks for sending that through. Try changing the child theme styles loading to just this:

    wp_enqueue_style( 'graphene-parent', get_template_directory_uri() . '/style.css', array() );



    Thanks – this is better than it was… I now get the following errors appearing at the top of the webpage:

    Notice: Undefined variable: child_handles in /home/jow0mii4q4m8/public_html/wp-content/themes/graphene/inc/scripts.php on line 254

    Warning: Invalid argument supplied for foreach() in /home/jow0mii4q4m8/public_html/wp-content/themes/graphene/inc/scripts.php on line 254

    You may ignore that notice for now. We’ll include a fix for it in the next theme update.

    To prevent the notice from appearing, try setting WP_DEBUG to false.



    Thanks again… I just wanted to check it was OK before setting wp_debug to false.
