Hello,

I have a website in which I want to replace the menu bar. I have created the menu using html and CSS. The Css file is a separate file. I have included the sidebar using include sidebar.html. The sidebar does shows but all the rest of the page is displayed wrongly. Also the sidebar is not complete, two last button go outsite the bar.

<?php

if (function_exists('get_thethe_image_slider')) {
        print get_thethe_image_slider('Slider Name');
    }

// Exit if accessed directly
if ( !defined('ABSPATH')) exit;


?>

Problem may be in closing DIV tags... make sure HTML tags are closed properly..

I don't see any divs open. That's my HTML sidebar
