Author bio displayed on post page?

TwentyTwelve has that, but it’s too smart, it will appear only if you got at least 2 authors in that site. There are 3 ways I can think of to make it appear.

1.
Just register another user and publish at least one post and there you got it.

2.
Copy over content.php to your childtheme and delete out this
&& is_multi_author() in around line 47

3.
Put this add_filter( 'is_multi_author', '__return_true' );
in your childtheme’s function.php

Works great. Thanks!

Which one of the three options worked for you ivanjunge?
