[4.17] Print String doesn't work

After installing Unreal 4.17 and converting my project from 4.16, I can’t see any print strings debugs I do, and, because of other functionality, I am sure that the event is being triggered. No screen and no log information are shown.

Hello, PrintScreen does work on 4.17. Could you please erase and reimplement some of those? Just to refresh the nodes to be created on 4.17.
