Quick Tips

  • Only extensions which support the Joomla! update system will be listed in this screen. If you use extensions which do not support the new update system or you are not sure, consult the extension developer's website.
  • It is critical to keep your extensions up-to-date. Failure to do so may expose a vulnerability in your Joomla! installation which can be exploited by hackers.
  • It is recommended to backup your Joomla! installation files and database before attempting to update extensions or the Joomla! installation itself. This will ensure that you can restore your Joomla! installation to its previous state if the update fails or causes unexpected results.
