It affects all websites on the server, and we cannot see it in the PHP files. So we believe it is in the server somewhere. We require somebody who can find, identify and remove the virus. We also need to update Debian and Plesk without breaking our websites. We have many complex OpenCart websites operating on this installation, so we must not cause any damage, and we must limit downtime. Looking for an experienced Linux developer who can start right away.
