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 -> Manage -> Update.
Joomla will show you a list of all extensions that have a new version.
For the purpose of this tutorial we will update the jHackGuard security plugin developed by us to its latest version. To do this, place a check next to the plugin name and press the Update button at the top left part of the page.
Well done! You've updated the jHackGuard plugin to its latest version!
