[Action Required] No "Movie-Tab" in the Webfrontend (1 Viewer)

[vel_tins]

Today, I installed MePo 1.2.3+TVServer+MPExtended Service 0.4.3+MPExtended WebMediaPortal 0.4.3
on two different machines.
On both machines, I have a missing "Movie-Tab" in the Webgui.
So I am unable to access my movies remotely.
There are two movies in the database.
If somebody needs some logs, please tell me.
thanks in advance
EDIT: Even when I access MPExtended via Ampdoid, the movies doesn't show up.

Do you have moving pictures installed and configured?

No, no plugins. Just a "stock" installation.
Edit: After I have logged out and in from Webfrontend and Ampdroid, everything seems to work now.
But I will have a look a "moving pictures"
