Adding author's name to post

The author’s name does appear, but over the post title

I meant above the post, not over. My bad!

hello there,

i just did a look to the theme you use and the author appear without any problem. the theme use a shortcode on the file :

omega/partials/entry-byline.php :

echo apply_atomic_shortcode( 'entry_author', __( 'Posted by [entry-author] ', 'omega' ) );

So just leave it this way and remove what you add to single.php

If you want to add the author on another place just insert : [entry-author] where you need !

@templates4all:
I followed your suggestion and removed the line of code I had added to single.php (by the way, I use a child theme of the Omega theme). The problem remains. Under the post title only this appears:

Posted on October 21, 2013

No author whatsoever. To be continued…
Thanks anyways!

@templates4all
You put me on the right track! As a matter of fact, in omega/partials/entry-byline.php these lines of code can be found:

if (is_multi_author()) {
		echo apply_atomic_shortcode( 'entry_author', __( 'Posted by [entry-author] ', 'omega' ) );
	} else {
		echo apply_atomic_shortcode( 'entry_author', __( 'Posted  ', 'omega' ) );

But as you can see, Posted by [entry-author] only applies (as I understand it) to multi-author websites, whereas mine is a single author site. I thus modified the code into this:

if (is_multi_author()) {
		echo apply_atomic_shortcode( 'entry_author', __( 'Posted by [entry-author] ', 'omega' ) );
	} else {
		echo apply_atomic_shortcode( 'entry_author', __( 'Posted by [entry-author] ', 'omega' ) );

and bingo! that was it.
Thanks again!

ohh glad you made it, i really didn’t notice this. good job ??

Well, thanks again for the hint. As a newbie, looking inside the omega/partials folder isn’t something I would’ve thought of in the first place! I’m still dabbling into code… bit by bit!
