NetApp VSC 6.0 Plugin won't show up in WebClient 6.0

We recently updated our vSphere Server 5.5 to 6.0 and the NetApp VSC Plugin from 5.0 to 6.0.

Now the Plugin won't show up in the WebClient as it did before the upgrade.

Has anyone the same issue? Is there a solution for it?

The backup jobs defined before the upgrade are running.

Thanks
