[kronolith] no Subscription URL shown

[Michael]

Hi!

Since I've updated my Horde Installation to Horde5 i dont see the 
Subscription URL for my Calendar any more.
Firebug shows the error "TypeError: $(...) is null $('kronolithCalendar' 
+ type + 'LinkImport').up('li').show();", there is no error in the 
webservers logfiles.
I also dont see the Feed URL and the Embed Script. For the Task List the 
Subscription URL is displayed.

Does anyone have an idea, how to fix this?

Versions: Horde 5.0.3  with Kronolith 4.0.3
