The widget will be there but nothing else is
That’s perfectly normal in many themes. The widgets replace the standard sidebar content and the replacement effect happens if you use 1 widget or 6.
If this isn’t what you want you will need to edit sidebar.php and look for
<?php endif; ?>
</ul>
</div>
Move the line <?php endif; ?> to immediately after
if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar() ) : ?>
This will allow you to display widgets at the top of your sidebar and yet still allow you to retain the standard sidebar content immediately below.
With regard to points 1 and 3, it sounds like you have introduced validation errors into the theme’s markup but without seeing your site, it’s impossible to say for sure or to offer any further suggestions.
OK–I will try to do this and get back to you. Thank you for your reply. “Confused”
