    Additionnal information.

    Selecting run immediate from the edit snapshot screen does work. However, when I leave the running now screen to navigate to another page while snapshot is running, will stop the backup process.

    Error log included:

    Hey Denis,

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

    Are you using the latest Snapshot release? If not, please update the plugin.

    This behavior however is most likely caused by WP Cron not functioning properly. WP Cron is based on the site hits (visits) so the more hits the better it works. Also there’s always a chance that something’s blocking/breaking it. It might be for example another plugin that’s interfering with Snapshot or that’s using WP Cron in a non-standard, WP Codex non-compliant way.

    That said, here’s what I’d do:

    1. Disable all the plugins except Snapshot and check for the issue. If Snapshot works fine, try to enable plugins one-by-one until the issue appears again. You’ll find the plugin that breaks WP Cron this way.

    If it doesn’t help

    2. Try switching WordPress to a real server’s cron instead of WP Cron (sometimes called also a “pseudo-cron”:wink:. To do this:

    – in your wp-config.php file add this line:

    define('DISABLE_WP_CRON', true);

    – in your server’s admin panel find the “Cron jobs” (or similarly named) section

    – add this command:

    wget -q -O - http://yourwebsite.com/wp-cron.php?doing_wp_cron >/dev/null 2>&1

    Let me know if it helped, please!

    Regards,

    Adam
