Are you using encryption: no

Client configuration

Browser: Firefox

Operating system: Win8.1

The problem I found was the path for the svg-icon as shown in the following screenshot:

Only the calendar app is missing the nextcloud (part of the path). All other apps start with nextcloud/restOfPath/

[georgehrke]

That's really weird, because contacts and calendar use exactly the same routine to generate the path:
https://github.com/nextcloud/calendar/blob/master/appinfo/application.php#L102
https://github.com/nextcloud/contacts/blob/master/appinfo/app.php#L35

[georgehrke]

Though it's weird that the contacts app uses a callback oO

The same problem appears with the standard-menu. So it's not a problem of the direct-menu-app.

Doc says closure is preferred, will try that:
