Mi Interface is gone

both side bars are removed, Logout does nothing.

I have logged out earlier the day and logged in again. Without closing the browser.

After that the counters where working again, but the rest was gone.

I will close the browser and reopen it after transmitting this message. If there is nothing additional, it works as expected.

Update:

Not working. I close and wipe out browser cache.

Update:

still not working
