Missing new directory replace during upgrade

Especially script-loader.php at the bottom of the page. Still loading from WP-admin.

Hi,
Thanks for your feedback, can you send the exact steps to take to replicate the issue? e.g. plugin update within Plugins area or Dashboard? Use inline update or bulk?

Thanks

If you run update from /update-core.php, there is a iframe, which contains upgrade messages and progress. In this iframe (update.php?action=update-selected...), there is script at the bottom, which include this – /load-scripts.php?c=0&load%5B%5D=hoverIntent,common,underscore,wp-util,wp-a11y,updates&ver=4.9.2'.

It’s genereted by iframe_footer() from wp-admin/includes/template.php.

I tried to use a lot of filter hooks, but without expected result.

Hope this works, but no replacing the content from iframe_footer():

add_filter('wp-hide/ob_start_callback', function ($buffer) {
    global $wph;

    $admin_url = $wph->functions->get_module_item_setting('admin_url');

    return str_replace('/wp-admin', '/' . $admin_url, $buffer);
});

So for my testing, with expected result, I hardcored this:

function wp_hide_print_scripts()
{
    global $wp_scripts, $compress_scripts, $wph;

    $admin_url = $wph->functions->get_module_item_setting('admin_url');

    $zip = $compress_scripts ? 1 : 0;
    if ($zip && defined('ENFORCE_GZIP') && ENFORCE_GZIP) {
        $zip = 'gzip';
    }

    if ($concat = trim($wp_scripts->concat, ', ')) {

        if ( ! empty($wp_scripts->print_code)) {
            echo "\n<script type='text/javascript'>\n";
            echo "/* <![CDATA[ */\n"; // not needed in HTML 5
            echo $wp_scripts->print_code;
            echo "/* ]]> */\n";
            echo "</script>\n";
        }

        $concat = str_split($concat, 128);
        $concat = 'load%5B%5D=' . implode('&load%5B%5D=', $concat);

        $src = $wp_scripts->base_url . "/{$admin_url}/load-scripts.php?c={$zip}&" . $concat . '&ver=' . $wp_scripts->default_version;
        echo "<script type='text/javascript' src='" . esc_attr($src) . "'></script>\n";
    }

    if ( ! empty($wp_scripts->print_html)) {
        echo $wp_scripts->print_html;
    }
}

add_filter('print_footer_scripts', 'wp_hide_print_scripts');

And it works well.

Is it good described now? Looks like the problem is in AJAX (iframe) upgrading of plugins/templates/languages.
