"Back to microblog" broken when logged out

Hi there,

we are using the Microblog and it looks great. :) Until somebody is logged in, the “Back to microblog” at the bottom of a blog entry is displayed correctly. But if you are not logged in the link is not visible and the icon on the left side is hidden by that triangle.

Example: https://diginauten.com/diginauten/microblog/placeit-jetzt-auch-im-abonnement/

Could you please help us?

Regards
Maria
