Hello,  
I am encountering following two issues:

1. I get 'Application Not Found  
No application was found at this URL. Try going back or choosing an app from the menu.' when trying to access dashboards.
2. See attached

![kibana message](https://us1.discourse-cdn.com/elastic/original/3X/f/1/f190d26dd971985ada299eb8d9e7ab9582b9f7c2.png)

Could these be related? any ideas?

Thanks!

It shouldn't be. This message might affect only email links created by Alerting plugin

For instance, in alerting, we append a link back into Kibana for the rule that caused the email to be sent, if the config is set. If not, we don't generate a link. That's it.

Because some folks have misunderstood this to mean that alerting won't work at all without the setting.

Could you provide an example of a link? There have been several refactoring between these releases but we do our best to keep a URL valid.
