Hide meta property="article:author"

Add this to your functions.php

function my_wpseo_og_article_tag( $content ) {
	return '';
}
add_filter( 'wpseo_og_article_tag', 'my_wpseo_og_article_tag' );

I always get a white page when I add this code. ??

The code works fine, it is copy&paste from a working site.

But I was reading too fast and just saw now that you do not want to remove the meta for tags (which would be “article:tag”) but the author.

So the code should be like this in your case (untested):

function my_wpseo_og_article_author( $content ) {
	return '';
}
add_filter( 'wpseo_og_article_author', 'my_wpseo_og_article_author' );

Hm, I’m confused. When I copy that lines into my fuctions.php I always ge a blank page. Maybe I’m doing something wrong?

Your provided code is on the bottom…

It’s the wrong file. Add the code to the file functions.php of your theme.
