Hello,
Here is my site and the page in question:
http://dkmmobilestudios.com/?page_id=14
First, I will point out that I am terrible with code, so please explain things like you are talking to a caveman.
I want to hide the author information on all posts. I don't care about the other meta info. I would really like to avoid creating a child theme. I don't mind if I need to change the code again every time I download an update. Can someone provide me with the correct code and where to place it?
