I have updated my site manually, now I get below mentioned notice in the front and backend:

Notice: register_sidebar was called incorrectly. No id was set in the arguments array for the "Main Sidebar" sidebar. Defaulting to "sidebar-1". Manually set the id to "sidebar-1" to silence this notice and keep existing sidebar content. Please see Debugging in WordPress for more information. (This message was added in version 4.2.0.)

How to fix this?

1. Find file where is register_sidebar ( must be on theme folder or plugins )

2. add ID to sidebar

   register_sidebar( array(
      'name' => __( 'Main Sidebar', 'theme-slug' ),
   
      'id' => 'change_me',  // Add only this line
   
      'description' => __( 'Widgets in this area will be shown on all posts and pages.', 'theme-slug' ),
      'before_widget' => '<li id="%1$s" class="widget %2$s">',
      'after_widget'  => '</li>',
      'before_title'  => '<h2 class="widgettitle">',
      'after_title'   => '</h2>',
    ) );
   

Or you can just disable notification in wp-config.php

edit WP_DEBUG to false

define('WP_DEBUG', false);

Looks like you have a very old theme. You'll have to search the functions.php file for register_sidebar and make sure the $args follow the format mentioned in the codex.
