Overview

This screen is accessed from the back-end Joomla! administrator panel. It is used to update extensions that are installed in your Joomla! installation.

How to Access

  • Select Extensions → Extension Manager from the drop-down menu of the Joomla! Administrator Panel. Then select the Update menu item in the Extension manager screen that appears.

Description

This screen allows you to update installed extensions. The extension update feature is new to Joomla! 1.6 and you will only be able to update extensions which support this feature. For extensions which support this feature, you will be able to perform an in-place update of the extension without having to upload and install the updated extension files like you did with previous versions of Joomla!. The update feature utilizes standard HTTP connection mechanisms to download the extension update files from a remote update server.

Quick Tips

  • Only extensions which support the new Joomla! 1.6 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.
