hi @nikpetrenko then is there something I can do about it for the actual 16.3 version and later? Is there a way I can output a piece of log to investigate where this issue comes from?
PS: I had already met with this same issue on Dec. 23rd, using the version 15.10.2 : How to remove an entry in the navigation bar when related page does not exist? - #4 by jmarkoll
So do you still think it is related to your latest fix for the Ukrainian language? Maybe it is unrelated?
