My Editor keeps setting bShowOnScreenStats=True to False. This causes Print String to be no longer visible in the Editor.
The Setting is in the EditorPerProjectUserSettings.ini File under “\Saved\Config\Windows”.
I only can see Print String again, if I change that value back in Notepad. This happens with my Project in 4.26, 4.27 and 5.0 EA.
It usually happens when a certain Blueprint is involved.
