We had an independent security person test our site last week and he found a security issue in Simple Renew.
Our developer fixed the issue and we've released a new version of Simple Renew. Please download the latest version of Simple Renew and upgrade to it at your earliest opportunity. Alternatively, you can upgrade from Joomla's update manager.
Joomla! just released their last beta release 3.5.1. We will need to wait a little longer for the stable version.
For those of you keeping your sites up to date, this new release will be a common procedure. However, if you have not been updating your Joomla site, findings reveal the need to upgrade/migrate to the latest stable version. Doing this will eliminate risks from vulnerabilities possibly found in old versions.
Please, don't become part of the statistics.
Why migrate your site?
We cannot explain this better than the good folks from Joomla.org. Read their reasons HERE. In short: you NEED to upgrade your site!
