Mostly if they are stacking it would a css thing — Ul/LI line-height or bottom margin

Not sure about exact tutorial but it generally is not that hard
a sidebar-widget function would look like

if ( function_exists('register_sidebar') ) {

	register_sidebar(array(

		'id' => 'post-sidebar',

		'name' => 'Recent Post',

		'before_widget' => '<div class="col %2$s" id="%1$s">',

		'after_widget' => '</div>',

		'before_title' => '<h2>',

		'after_title' => '</h2>'

	));

And than on your static page (once you have added the recent post widget through (appearance > widgets )
just add a DIV tag where you would want to display it

<div id="your-post">
<?php if (is_active_sidebar('post-sidebar')) : ?>
</div>

Hey kevin
I believe AVADA being a paid theme you should first approach the theme developers for your issue.

Best practice if you just want to remove it from homepage
create a child theme
create a functions.php file in it
add this function

<?php
if(is_home()){
echo '<style>
.entry-title, .entry-title a
{
display:none;
}
.entry-content, .entry-summary
{
padding:0;
}
.left-sidebar #secondary {
    float: left;
    margin-left: 10px;
    margin-right: 0;
    overflow: hidden;
    width: 18.8%;
}
</style>';

The last class edit
.left-side #secondary
would fix the images going out of your theme content area

@hagiangt, can you put your query in a new post so it easy to help

@jayavinoth — did it worked out ? did you try installing a new WP installation

can you printscreen your ftp view

if you have access to ftp rename your current theme folder to theme-old and it should be able to pick default theme twentyeleven (if you havnt deleted it and it is still in your theme directory) but to the looks of it, i would suggest make a new directory install a fresh copy of your WordPress, install your theme (which you are currently using) and see if this is still happening

IMP: do backup your current database as well.
