Hide author and icon | WordPress.org

Hi,
Check your settings in appearance to see if your theme gives you the option to not display post metadata. Otherwise add the following custom CSS:

.entry-author { display: none; }

.single .entry-author{ display : none ! important;}

Please paste the above CSS code in Appearance -> Customize -> Additional CSS

I hope this will help you.

Thank you, it helped! have a nice day
