    Hello Seongsoo,

    I hope you're well today and thank you for your question!

    This error means that the script timed out in five seconds. There may be a number of reasons for this but usually it's related to the "load" of your site and/or server resources as both this factors affect the performance of the site.

    In order to fix it please please follow these steps:

    1. Make sure that WordPress is granted enough memory by adding following line to the "wp-config.php" file of your site:

    define('WP_MEMORY_LIMIT','256M');

    This line should be added above the "/*That's all, stop editing" line.

    2. If above didn't help then additionally:

    - create an empty file with the ".php" extension, e.g. "increase-http-timeout.php"
    - paste following code inside:

    <?php
    function wpmu_increase_http_timeout( $timeout ) {
        return 30; // let's change default 5 seconds to 30 seconds
    }
    add_filter( 'http_request_timeout', 'wpmu_increase_http_timeout' );

    - save the file and upload it to this folder on your server: "/wp-content/mu-plugins"

    If there's no "mu-plugins" folder inside "wp-content" folder, please create it.

    Let me know if this helped!
    Best regards,
    Adam
