Websites running the first version of Joomla! are becoming increasingly targeted by hackers, so we urge you to upgrade as soon as possible to avoid your website being compromised. All versions of Joomla! 1 are no longer being patched by the developers as it is end of life, so you will need to upgrade beyond this.
If you are running a v1.x site we would urge you to upgrade to either version 2.5 (recommended for production use) or version 3.0 (recommended for developers and early adopters).
To find out which Joomla! version you’re currently running, check the footer of your administration panel or look in libraries/joomla/version.php. Please remember to check old and abandoned websites as well – these also need upgrading or deleting.
For general advice about upgrading, please refer to this Upgrading and Migrating Joomla! documentation.
We also have one-click installs available for versions 2.5 and 3.0 if you wish to install a completely fresh version and migrate your existing website. Simply head to the eXtend control panel to get started. If you’re a Reseller, you may first need to activate more recent versions of Joomla! from the Reseller Control Centre by editing your hosting package options.
Resellers, please check your customers’ websites. If there are any running Joomla! version 1 in any form, please strongly encourage your customers to upgrade as soon as possible.
Other security considerations
Please remember that upgrading to the latest version of Joomla! isn’t a cure-all solution, and any third party add-ons or templates can have potential security flaws. Be vigilant when installing any extras, delete old files you aren’t using any more, and try to download from official trusted sources.
