@tgd: MH Newsdesk lite has a conditional for the author box based on if there is an author bio or not. So actually the easiest way is to simply delete the author bio through the WordPress dashboard (as mentioned before) because it’s not needed anyway when there is no author box.
There is no coding at all required for this when using MH Newsdesk lite and doing it this way even allows to show the author box on a per user basis. If there is an author bio, the author box will be displayed and if not, then the author box won’t be displayed out of the box.
The only instance where coding would be required is when someone wants to remove the author box in general and don’t let users make this decision – for example for multi-author sites where the admin wants to get rid of the author box on a global scale.
However, on the other hand, when having a multi-author site, it probably would make sense to give the authors some attribution for their work by showing their stuff. ??
