I had deleted a domain in the admin panel. Later I remembered that there was still a cron job going on. After trying to delete the cron, the Cron Jobs section disappeared under System Tools. Under Settings / System administration / Plugin administration stood in Cronjobs:
> An unexpected error has occurred:
>Plugin::CronJobs::_writeCronTable: Could not find `vu2017' user entry in passwd file.
I can not even uninstall or delete the plugin now. Can I manually delete the erroneous entry?
