In most cases updating your components, modules and plugins is an easy task. First, you need to access your Joomla 3 admin page and go to Extensions -> Extension Manager.
Well done! You’ve updated the jHackGuard plugin to its latest version!
Important! Not all Joomla extensions can be updated through the Joomla Extension Manager. This is why it is important to check the official websites of the extensions you’re using. If possible, subscribe to their RSS feeds for new versions in order to be informed immediately after a new release is launched.
