    Hi,

    Did you try basic troubleshooting by deactivating other plugins and themes to see if it resolve the issue?

    Let me know how it goes.

    Best Regards,

    I deactivated BackWPUp and it resolved the issue… Seriously – even without knowing your plugin in detail, the stack trace pretty obviously seems to indicate that BackWPUp has a problem handling some saved config information (probably from earlier versions).

    And no, I did not even start to disable 20+ other plugins.

    Hi,

    I apologize for the inconvenience — we’ve looked into it and were able to replicate the issue on our end as well.

    This is caused when backup jobs were originally created in version 4.x without fully saving the General tab (for example, jobs set to run via WordPress cron but never actually saved with all required settings). In version 5.x, some functions expect complete data (like a cron expression), and when it’s missing or null, it triggers a PHP fatal error.

    The most reliable fix is to reinstall the plugin, which should reset the affected configuration. Make sure to reconfigure your backup jobs after reinstalling, especially if they were migrated from version 4.x without edits.

    We’re also tracking and patching this as part of our ongoing improvements.

    Please let us know if the issue persists after reinstalling, and we’ll gladly assist further.

    Best regards,
