Whoops\Exception\ErrorException: Call to a member function directoryExists() on a non-object in file /var/www/html/admin/modules/backup/functions.inc/class.backup.php on line 423

Module admin, check shows backup up to date.
Any idea how to fix this?

Thanks.

@Hawkeye What version of Backup & Restore are you running?

this should be corrected in the next release… It means you likely have an auth error, or an assumption was incorrect. This section of code was redone in the next release so assumptions are a bit different.

It looks like a new version is in edge.
