Jetpack update, site now unreachable with error 500

    I run a personal site at https://www.fredriley.org.uk/wordpress, I log in as admin to run a couple of plugin updates, I run the Jetpack update, it stalls, I try to get back into the site and get error 500 – D’OH!!

    I search Google for Jetpack and 500, try the temporary fix from 10 months ago, editing the Jetpack require-lib.php to change the lib path, save and reload – 500 error. D’OH!! D’OH!!

    So I delete the folder wp-content/plugins/jetpack via FTP, reload the site, 500 error persists. D’OH!! ^3

    Short of trashing the whole site, are there any suggestions as to how I can get to the site Dashboard to carry out repairs?

    It’s disappointing that a routine update of a WordPress-official plugin brings the site down, and may well cost me many hours to get it back. Live and learn ??

    I’ve now deactivated all plugins by renaming the wp-content/plugins directory, as advised by this article, and now the site works and I can get to the Dashboard. I guess I’ve now to go through the tedious business of re-activating plugins one by one. However, the problem was definitely caused when I was updating Jetpack and another plugin (Ninja forms I think), and the Jetpack update hung.

    That would indeed be a good way to go. Let me know how it goes!

    Since the problem remains when Jetpack is completely removed from your site, Jetpack is most likely not the cause of the issue.

    Once you find the plugin that causes the issue, I would recommend adding the following to your site’s wp-config.php file, to find out more about the issue:

    
define( 'WP_DEBUG', true );

if ( WP_DEBUG ) {

        @error_reporting( E_ALL );
        @ini_set( 'log_errors', true );
        @ini_set( 'log_errors_max_len', '0' );

        define( 'WP_DEBUG_LOG', true );
        define( 'WP_DEBUG_DISPLAY', false );
        define( 'CONCATENATE_SCRIPTS', false );
        define( 'SAVEQUERIES', true );

}

    Your wp-config.php file may already include a line that says “define(‘WP_DEBUG’, false);”. You can remove it, and replace it by the code above.

    Once you’ve done so, check the wp-content/debug.log file for errors. It will give you the exact file and line where the error is happening.

    You can then replace define('WP_DEBUG', true); by define('WP_DEBUG', false); in the code above.
