delete info from share

Hello,

I’m really beginner at wordpress so I’m sorry if my problem isn’t really a problem.

I started using mashsharer today with my new website and it works correctly, but I need that it will not add author user everywhere (in the picture below, it’s in two places- “written by krissyld” on top and vlnd.ee | krissyld below. http://puu.sh/hSjlg/a4511dfda0.png

Is there any way to erase these things from posts?

Thanks in advance!
