Where does the mysterious blue bar and question mark come from (when logged in as admin)? When I'm logged in as an admin, I see a blue bar at the top of the page, with a question mark in a circle, but no text. This is how it looks like:



And the markup is:

&lt;div class="region region-help alert alert-info"&gt;


I guess it's some kind of alert, but obviously there's no text, and nothing I can see in any of the logs that might be related either.

Anyone knows what this might be and how to fix it?
I think You should try to:


search Your modules or themes directory for usage of drupal_set_message function or dsm if You are using devel module. 
check trigger module settings for User under admin/structure/trigger/user
check theme template for empty container with alert-info class
