No UMC after update to 4.2 from 4.1-5

UCS - Univention Corporate Server
#1

Hello,
i upgraded my UCS from 4.1-5 to 4.2 now i only get a blank page when trying to access “https://my.ucs.com/management/console”

Seems like i also have a problem with this bug: https://forge.univention.org/bugzilla/show_bug.cgi?id=41782
I removed the attribute @univentionPortalEntry and @PortalEntry from the config.
As i had this message in my logs:
