Remove "Home" On Right Sidebar

Hi Chachandz, hope this works with you.
Open your sidebar.php then look for this line:

<div class="sidebarwidget">
<?php wp_nav_menu( array( 'theme_location' => 'primary' ) ); ?>
</div>

All you need to do is to comment out.
So it will look like this:

<!--<div class="sidebarwidget">
<?php wp_nav_menu( array( 'theme_location' => 'primary' ) ); ?>
</div>-->

I preferred hiding than deleting it to restore the code back easily if it doesn’t work.
