Yes, we’ve discussed this at length in other topics, like this one.
Short version, the easiest fix is to upgrade to Backlight 5. If you don’t want to do that, then you can follow Rod’s tutorial on how to fix it yourself.
And if that’s also a non-starter for you, then contact me privately with FTP credentials and a login for Backlight’s admin, and I can fix it for you, usually within a day or two of receiving that information.
