Rename Calendar-/Group Site resume errors

[Mark.B]

Calling staff stupid isn't likely to endear anyone towards trying to assist.

I'm not sure if the calendar supports renaming,

Because I am german, I change adresses of some pages of vB to native language terms. Result: It is impossible to create groups or calendar entries now. On creating a group I get error message "Ungültiger Wert '' für Parameter $nodeid in Method vB_Api_Content_Channel::canAddChannel". Calendar entries go into database but will not displayed on calendar.

My question is: Are vB programmers totally stupid? On version 5.2.3 such primitive errors? Do they know their job? My advice: Fire them and fire the developing master!

Don't believe in support anymore. Found an old thread there from 2015 including the same error.
