After one or more boxes are checked, click a toolbar button to take an action on the selected item or items. Many toolbar actions, such as Publish and Unpublish, can work with multiple items. Others, such as Edit, only work on one item at a time. If multiple items are checked and you press Edit, the first item will be opened for editing.

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.
