Since 5.8, theme error foreach script-loader.php line 2652

  • WP v 5.8
    PHP 7.4 (also tried 8.0, no diff)
    Host 1&1
    2 sites running WP since 2007, so experienced user here.

    Since 5.8 update, using a custom theme since 2007, I am seeing printed out on every page the following error message at the end of the page:

    Warning: Invalid argument supplied for foreach() in xxxxxxxx/wp-includes/script-loader.php on line 2652

    A google search shows MANY other users websites are showing same message relating to line 2652. And I have 2 sites, and both are affected.

    Message is not present if I use a modern 2021 theme, so it is related to my custom theme somehow. That said, the theme is worked perfectly since 2007 and is very basic, so a WP change caused this problem.

    Also, I notice that if I remove:
    <?php wp_footer(); ?>

    from footer.php, the message goes away, but it seems as though that code SHOULD be present in all themes, so that is not a solution.

    I have also experimented with tweaking the themes functions.php file, but even making that file empty does not solve the problem.

    Help will be appreciated, thanks.

    Also, further information… the error message does not display if I am logged into the site and viewing the site. But logged out — the way any visitor would view the site — the error message is printed.

    I want to solve the problem, not just hide the error message.

    OK, I will answer the question myself, and share with anyone else who may be having same problem.

    In your HEAD section, you are missing a PHP statement.

    Example of what it should have:

    <head>
    <!– First add the elements you need in <head>; then last, add: –>
    <?php wp_head(); ?>
    </head>

    So, the problem is that I was missing the line:
    <?php wp_head(); ?>

    Putting that directly before the </head> tage fixes the problem.

    And FYI, that is found in your header.php file

    You can easily fix this without using the wp_head() by adding $wp_styles = wp_styles() in your own custom header code.
    wp_head() adds a lot of data that you might not always want to use.

    <?php $wp_styles = wp_styles(); ?>

    @segevmoran – Thank you for your solution. It worked on all my custom theme pages where I had decided to not use wp_head(). Regards.

    @festusdog : Thank you very much for posting the solution! ??
    @segevmoran : Thank you for your special solution ??
