Enfold theme - how to remove info from posts/blogs that is sharing on social networks?

Good day,

i'm using wordpress and Enfold theme and my client doesn't won't to share unnecessary information (posted by, date and location). When clicking share button like fb or twitter they automaticly generates info. Maybe someone knows how to remove it? I know there is support, but i don't have theme key to registrate in those forums. Example - here

Thank you for your time.
