How to Upgrade WordPress plugins.

Just updating WordPress core won't make your WordPress fully secure. Updating a plugin installation is equivalently important as updating the WordPress core. The Vulnerability in one of these plugins can be end up in hacked websites.  

One Click plugin update

Like WordPress core, WordPress plugins can also be upgraded in one click method through WordPress dashboard. You just need login to WordPress dashboard, Go to Updates section. If there are plugins to be updated, they will appear here. To update your plugins, select them and click on the ‘Update Plugins’ button.

Automatic Updates

If you wish you can also set WordPress to automatically update plugins and themes. Automatic updates for plugins is disabled by default. To enable automatic plugin update, you will have to add filter into the functions.php file of your theme or in a plugin.

// Enable automatic updates for plugins
add_filter('auto_update_plugin', '__return_true');
