If you have a bbPress forum on a site running the Genesis framework, the bbPress Genesis Extend plugin is a great tool. It helps bbPress integrate with your Genesis child theme so that (hopefully) you don’t need to add a lot of CSS changes to your stylesheet.
One thing it may not do is remove the Genesis author box from your forum pages. I nearly lost my mind trying to hide the author box on a client’s site; nothing I did was working and the client was becoming frustrated. Today, with the help of the bbPress Genesis Extend plugin’s author, Jared Atchison, and some other awesome people in the Genesis community, I finally found a solution that works.
If You’re Using an XHTML Genesis Child Theme
For older XHTML child themes, add the following to functions.php:
Keep in mind, if your child theme positions the author box somewhere other than
genesis_after_post, you will need to change the hook in the above code.
If You’re Using an HTML5 Genesis Child Theme
For newer HTML5 child themes, add the following to functions.php:
Again, you may need to change the hook if your child theme has moved the author box.
That’s all, folks! Once you insert the code above into functions.php and save, you should still see the author box on single posts, but not on your bbPress forums.
