Yes. WordPress.com is safer than WordPress.org because WordPress.com has a community and a team which keeps a check on security standards. On the other hand, in WordPress.org you will be more reliant on your web hosting provider. If you are using WordPress.org you need to make sure that your host maintains a gold level security standards.

WordPress.com and WordPress.org are two different platforms with different approaches to security.

WordPress.com is a hosting service that provides users with a managed WordPress platform. In this case, security is managed by the WordPress.com team, who handles all the server maintenance, software updates, and security measures. WordPress.com also has strict security protocols, including SSL certificates, DDoS protection, and firewalls. They also monitor all sites on their platform for suspicious activity and malware.

This means that users are responsible for their own website's security, including server maintenance, software updates, and implementing security measures. While WordPress.org is secure, the level of security depends on the individual user's implementation of security measures.

So, in terms of security, WordPress.com may be considered more secure because the platform is managed by a team of experts responsible for maintaining security protocols. However, this also means users have limited control over their site's security measures. In contrast, WordPress.org gives users more control over their site's security measures but also requires them to maintain and implement those measures.

WordPress.com and WordPress.org are two different platforms that offer WordPress content management system (CMS) for creating and managing websites.

WordPress.com is a fully hosted platform that handles all the technical aspects of running a website, including hosting, security, and backups. On the other hand, WordPress.org is self-hosted, which means you need to find your hosting provider to host your website.

WordPress.com offers limited customization options and doesn't allow access to the website's core files. In contrast, WordPress.org offers full customization options, allowing you to modify the code and access the website's core files.

WordPress.com offers a limited number of themes and plugins to choose from, whereas WordPress.org offers an extensive library of themes and plugins that you can use to customize your website.

WordPress.com doesn't allow you to monetize your website with ads unless you upgrade to a paid plan. However, with WordPress.org, you have complete control over your website, including the ability to monetize it with ads and other methods.

WordPress.com offers various pricing plans, from free to premium plans with advanced features. In contrast, WordPress.org is free, but you must pay for hosting and other website-related services.

WordPress.com is a great platform for beginners who want an easy-to-use website builder. At the same time, WordPress.org is more suitable for advanced users who want complete control and customization options over their websites.

    'add_new_item'               => 'Add New Item',
    'edit_item'                  => 'Edit Item',
    'update_item'                => 'Update Item',
    'separate_items_with_commas' => 'Separate items with commas',
    'search_items'               => 'Search Items',
    'add_or_remove_items'        => 'Add or remove items',
    'choose_from_most_used'      => 'Choose from the considerable used items',

    'items_list'                 => 'Items list',
    'back_to_items'              => 'Back to items'
  );
  $args = array(
    'labels'                     => $labels,
    'hierarchical'               => true,
    'public'                     => true,
    'show_ui'                    => true,
    'show_admin_column'          => true,
    'show_in_nav_menus'          => true,
    'show_tagcloud'              => true,
    'rewrite'                    => array( 'slug' => 'taxonomy' )
  );
  register_taxonomy( 'taxonomy', array( 'post' ), $args );
}
add_action( 'init', 'custom_taxonomy', 0 );

• Save the functions.php file.
• Go to your WordPress admin panel and click on 'Posts' or 'Pages', depending on the post type you assigned your taxonomy to.
• Click on 'Add New' or edit an existing post/page.
• In the right sidebar, you should now see a box labeled with the name of your taxonomy. You can add new terms by clicking the '+ Add New Taxonomy' link.

That's it! You have now created a custom taxonomy in WordPress.

Here are the steps to successfully change the Homepage URL in Wordpress. Go to the function.php file in your WP theme and use this code:

function redirect_homepage() {
   if( ! is_home() && ! is_front_page() )
   return;
   wp_redirect( 'http://siteurl.com/news', 301 );
   exit;
}
add_action( 'template_redirect', 'redirect_homepage' );

We can do it 2 ways

• Before installation : Go to wp_config.php file and rename $table_prefix = 'wp_'; whatever you want.
• After installation : Go to phpmyadmin -> select your databse -> check all tables -> Add/Update table prefix.

$args = array( 'post_type' => 'blog', 'posts_per_page' => 10 );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
   the_title();
   echo '<div class="entry-content">';
     the_content();
   echo '</div>';
endwhile;
