Hi Thanks for this Plugin,
Is there a way to hide the title as well. The title of the page may be sensitive info.
Also just an observation. I think you have some slight mistranslations going on here so I have given a suggestion for this sentence. The option before this example needs similar corrections.
"If this box is check then content will show only to none logged-in visitors and everyone else will get the blocked massage"
"If this box is checked then content will show only to non-logged in visitors and everyone else will get the blocked message."
Hope this helps and thanks again.
