I'm a newbie so be nice: When I use the "Share > Post to Facebook" dropdown menu it creates a facebook entry that has the correct name of Website but it puts in the creator of the template. Can that be changed and if so where? Currently it shows: BY ALEKSANDER BACKO JELICIC and I need it to reflect my publisher name instead. When I did an inspect of item it referred me to this parameter. Where is it found? attachment [params] [external_author]
