Joomla software is actively being attacked and hacked by a “zero-day” vulnerability that must be immediately patched by your developer.
Read about it, and the fix, here: https://blog.sucuri.net/2015/12/remote-command-execution-vulnerability-in-joomla.html
We are actively seeing Joomla customer sites on our servers being hacked. Once the hackers hack your site they’ll send pornographic spam emails, attack visitors to your site, and steal your customer data. So its imperative that you contact your developer now and apply the patch in the link above.
Thank you for your prompt attention to this.
