Nikeo’s code has nothing to do with the database. You either have altered config.php or you’ve placed nikeo’s code outside php markup. Please quote the contents of your functions.php of your child theme and we’ll tell you what’s wrong.

You need to copy class-header-nav_walker.php in your child theme (replicating the same folder structure! – if you copy it in your functions.php you’ll get the same error again!) and modify (practically replace) the function start_el() with the code above, not add it. The error you posted is php’s way of saying: “Can’t have same function declared more than once, mate. Give it another name or delete one version.”

You already have the same function declared earlier, probably in the same file. Or in functions.php of your child theme, if that’s where you pasted the code.

In order to shed a little light on WP’s logic regarding child themes: whenever it needs a file from the theme, WP first searches in the child theme. If the file’s not there, it gets fed from parent. So, whenever you want to modify anything from the parent, copy the file to the same folder in your child theme and hack it away. This rule doesn’t apply to functions.php and style.css though.

Also, beware that when the parent gets updated, sometimes the files you copied to your child theme have been modified and you can’t benefit from the mods unless you copy again the original from the parent and make the mods once more (saving in your child theme).

Actually, it can be done (forget the code above):

.round-div {border-color: rgba(255, 255, 255, .5);}
.thumb-wrapper { height: 270px; border-radius: 300px;}

It was much easier than I expected. Don’t forget to upload 270 x 270px images for all the three featured pages or you’ll see the circles cut at the lower end.

You don’t need a plugin for that. I made this function. Of course, I could wrap it up and make a simple plugin out of it, but I’ve never been a fan of the plugin support hassle.
Add this to functions.php in your theme’s folder:

add_shortcode('gutt-u', 'gutt_get_user_attribute');
function gutt_get_user_attribute($atts = array()) {
	global $current_user;
	get_currentuserinfo();
	extract( shortcode_atts( array(
		'id' => $current_user->ID,
		'login' => '',
		'email' => '',
		'slug' => '',
		'field' => 'display_name'
		), $atts) );
	if ($login || $email || $slug) {
		if ($login) $gatt_user = get_user_by('login', $login);
		elseif ($email) $gatt_user = get_user_by('email', $email);
		else $gatt_user = get_user_by('slug', $slug);
		}
	elseif ($id > 0) $gatt_user = get_user_by('id', $id);
	else return;
	if (in_array($field, array( 'ID', 'user_login', 'user_nicename', 'user_email', 'user_url', 'user_regitered', 'display_name')))
			return $gatt_user->$field;
		else return $gatt_user->__get($field);
}

How it works: Use [gutt-u] with id, login, email, slug and field parameters.

id – id of the user you want to retrieve data for; defaults to current user and function doesn’t return anything if id (or login, or email, or slug) is missing and current user is not logged in;

login – login (user_login) of the user you want to retrieve data for; overrides id, email and slug;

email – email of the user you want to retrieve data for; overrides id and slug;

slug – slug (user_nicename) of the user you want to retrieve data for; overrides id;

field – the field you want to retrieve from the user; defaults to display_name. It can be any default WP field or any user meta field as long as it exists, except user_password (I chose not to include it, but can be added to the fields array if needed).

Examples:
[gutt-u] => returns display_name of current user.
[gutt-u field=id] => returns ID of current user.
[gutt-u email=mail@domain.com field=some_user_meta_field] => returns the some_user_meta_field of the user registered with mail@domain.com.
[gutt-u slug=acub field=user_registered] => returns the date of registration for the user with user_nicename = “acub”

I doubt sanitization is needed. From the few tests I’ve made, if no user is found or if the field doesn’t exist, it just returns nothing.

@jason, feel free to put my code to good use if you find it useful. Thank you for a robust plugin.

Most likely it’s a typo. Try the replacement without the tag chars:
replace:

div class="brand span3"

with:

div class="brand span12"

Alternatively, eliminate your replacement, look at the exact source of your .brand div (select the logo in firefox and “View selection source”) and try to apply a replacement rule that will only match that element and nothing else in your page. To make sure the replacement works, copy/paste the string to be replaced from the source.

You’re welcome. You might want to save your logo with a bit of space to left and right. Now it’s glued to both sides on narrow displays. 30-40px in each side should do it. Narrow down your browser window to see what I’m talking about.

You only need to register new sidebars if you want to place additional sidebars in your page, in other places, while keeping the ones that are already registered.

Changing content of sidebars relative to the page you’re on is called Widget Logic and should be handled by plugins, not by themes. The most popular widget logic plugin for WP is called… Widget Logic.
