    Sorry about that!

    Could you try to reinstall the plugin from scratch?

    If that doesn’t help, could you try to increase the amount of memory allocated to PHP on your site, as explained here:

    If that doesn’t help, we’ll need to find out more about the error: could you add the 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 );

    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 activate Jetpack again. Once you get the Fatal Error, 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.


    Thank you so much for your response, it helps and I continue running JetPack flawlesly.
