Hi guys,

i get an error on my raspberry pi 3 if i want to configure the e-mail notification. (omv 3.0.35)

The XPath query '//system/notification/notifications/notification[id='cronapt']' does not return the requested number of 1 object(s).
Fehler #0:exception 'InvalidArgumentException' with message 'The XPath query '//system/notification/notifications/notification[id='cronapt']' does not return the requested number of 1 object(s).' in /usr/share/php/openmediavault/config/database.inc:172Stack trace:#0 /usr/share/openmediavault/engined/rpc/notification.inc(66): OMV\Config\Database->getByFilter('conf.system.not...', Array, 1)#1 [internal function]: OMVRpcServiceNotification->get(Array, Array)#2 /usr/share/php/openmediavault/rpc/serviceabstract.inc(124): call_user_func_array(Array, Array)#3 /usr/share/php/openmediavault/rpc/rpc.inc(84): OMV\Rpc\ServiceAbstract->callMethod('get', Array, Array)#4 /usr/sbin/omv-engined(516): OMV\Rpc\Rpc::call('Notification', 'get', Array, Array, 1)#5 {main}
