This notice is intended for customers who are using Joomla on their website(s). Joomla has release a new version 1.5.21 which is a security release. Please upgrade Joomla at your earliest convenience. Using old versions of Joomla leaves your site and the entire server vulnerable to abuse.
Joomla can be upgraded within your cPanel Control Panel under the Installatron or Softaculous icon. If your Joomla install is not listed under Installatron it may show up in Softaculous instead. We will check in a few weeks and upgrade any old versions of Joomla that still have not been upgraded. If you have any questions or concerns about this please open a support ticket using our Client Area.
