Hi all! I have just upgraded to 3.9 and noticed that there is a message on every page. 

For instance, when on front page, it says:

"This page is: General type: frontpage. Context Front page (context id 2). Page type site-index."

I tried accessing with an student account and the message is there, so there isn´t something just with the admin.

Any suggestion on how to remove it?

Thanks in advance!

Emilio
