Hello,
I deleted the filters from notification history and now I use ICINGA console its throwing error.
Fatal error: Method Icinga\Web\Widget\Announcements::__toString() must not throw an exception, caught Error: Class ‘Icinga\Data\Filter\FilterAnd’ not found in zend.view:///usr/share/icingaweb2/application/layouts/scripts/body.phtml on line 0
Thank you
