Thanks guys.
Besides the WordPress and Joomla sites which are completely down, our main site(playcasino.co.za) and other HTML sites are now displaying a warning when accessing it. As a matter of fact, all the websites hosted on this hosting account have been affected.
For the WordPress sites, we have reinstalled the latest version of WordPress and starting all over with a new host.
