Support » Plugin: Backup WD - Backup and Restore Plugin » Scheduler doesn’t like Sundays?

  • Resolved jonjennings


    WP version 4.9.1
    Plugin version 1.0.10

    I had some problems with a client who set their backup to run at 3:00 every Sunday. The plugin crashed with a fatal error which meant they couldn’t get into the backend to fix things.

    Checking through the crash log and the code, it seems that includes/buwd-cron.php:18 was calling CronExpression::factory(’00 3 * * on’)

    ‘on’ obviously isn’t a valid day name/number and so, several layers down vendor/aannnaa7/cron-expression-php5/src/Cron/CronExpression.php:130 was throwing an exception

    If I changed the day to be Monday then things are fine.

    Their job schedule page looked like

    Crash log:
