full-size banner

You have “span10 offset1” as class for your banner, probably ’cause you applied a snippet to change that class.
You have something of the sort in your child-theme functions.php

add_filter('tc_logo_text_display', 'your_logo_display');
add_filter('tc_logo_img_display', 'your_logo_display');
function your_logo_display($output) {
return preg_replace('/brand span3/', 'brand span10 offset1', $output, -1);
}

Change it this way:

add_filter('tc_logo_class', 'center_logo');
function center_logo($output) {
    return str_replace('span3', 'span12', $output);
}

Also I suggest you to add this to your child-theme style.css to restore the ability to click on the logo.

.navbar-wrapper.clearfix {
    clear: both;
}

🙂
Glad you solved!
