Orchestrator not responsive after installing patch 2017.1.6612

We upgraded orchestrator from version 2017.1.6522 to 2017.1.6612 after which all controls seem to stop working. I am currently logged in as admin, but even with all rights I can’t do anything. I can’t launch a job, create an asset, modify asset, … It seems everything to actually make a change doesn’t respond.
Any idea what could be wrong?

Also it is strange that the current Orchestrator version shows to be different than the package name, as it shows 2017.6610.
