500 Error with Jetpack 4.8 Update

@bizbookscloud @mrmikedavis If you’re willing to give the update another try, could you add the following to your site’s wp-config.php file first?

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, try to update Jetpack again. If the error comes back, check the wp-content/debug.log file for errors, and paste the results here. You can then replace define('WP_DEBUG', true); by define('WP_DEBUG', false); in the code above.

Thanks!

Thanks for the reply @jeherve

I have a couple demo sites where I may try the debug, but as for a live production site, no way. I would not recommend that or auto update plugins at all.

In looking at the sites that were impacted, the common feature is a caching program, either W3 Total Cache or WP Rocket, and all were on shared servers.

Start by adding following to your site’s wp-config.php file:

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 );
