I cannot see what is wrong with this- here is validator error:..
end tag for "ul" which is not finished …-sidebar"><ul id="footer-sidebar"></ul></div></div><div class="column-right"><… ✉ Most likely, you nested tags and closed them in the wrong order. For example <p><em>...</p> is not acceptable, as <em> must be closed before <p>. Acceptable nesting is: <p><em>...</em></p> Another possibility is that you used an element which requires a child element that you did not include. Hence the parent element is "not finished", not complete. For instance, in HTML the <head> element must contain a <title> child element, lists require appropriate list items (<ul> and <ol> require <li>; <dl> requires <dt> and <dd>), and so on.
here is the sect of code it came from:
<div class="column-middle"> <div class="footer-sidebar"> <ul id="footer-sidebar"> <?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('Footer Sidebar') ) : ?> <?php endif; ?> </ul> </div> </div>
