<div id="header">
     <div class="wrap">
          ...
     </div>
</div>

<div id="nav">
     <div class="wrap">
          ...
     </div>
</div>

<div id="footer">
     <div class="wrap">
          ...
     </div>
</div>

adding the following CSS:

.wrap {
    margin: 0 auto;
    width: 960px;
}

contrains the inside of each those sections to the set width, but allowing the outside container to span the full width.

If there is a #footer .wrap { … } or the like for the other sections it should be fine to leave them. Only ones to be concerned of are if a width is set to #header { … }, #nav { … }, ect., without targeting its inner wrap class since that will constrain the entire width of the section.

Let me know if this makes sense, if not I can create a little graphic when I have some free time to further explain.

add_filter(‘genesis_post_info’, ‘custom_post_info’);
function custom_post_info($post_info) {
$post_info = __(‘By’, ‘genesis’) . ‘ [post_author_posts_link] ‘ . ‘ [post_comments] [post_edit]‘;
return $post_info;
}

 if it doesn't remove it means it has been removed and modified from somewhere else. If you are running any genesis specific plugins I would check those files for "genesis_post_info". If it does get removed try setting a priority on the filter like [php]add_filter('genesis_post_info', 'custom_post_info', 20 );

the 20 will make the filter run later, can even set it at 100 to make sure it runs after all other modifications to the post info.

Sorry for not answering sooner, work got too crazy the other day and just started going back through my comments responding to any I missed.

Edit:
I found the issue. There were fancy quotes in the snippet. I have updated the code in the link above and should work correctly now.

Not sure why you have not answered my post. You say, “Place it at the bottom of your child themes functions.php before the “?>” if there is one; if not you can still put it at the end.”
My Focus theme functions.php does not have “?>” at the end.
I added the script as you suggested days ago and the site froze up, which resulted in my post above.
Am I missing something here? Am I required to pay a fee to get my script altered which I pasted at http://pastebin.com/bZ2fNSiW
Sorry, I just don’t get why you have replied to other posts here and not mine.
Please advise.

Here’s what in the function file:
$post_info = ‘by [post_author_posts_link] on [post_date] [post_comments] [post_edit]‘;

But as I said earlier my byline looks like this:

Is it possible the byline is being set somewhere else in the copyblogger template?
