Hello, I have been using Cubecart 3.0.20 for years and I have also linked it to additional custom-made backend. I know that since 3 yers it is open source, however I can't remove "Powered by Cubecart" from the page title. I am not able to buy a license key neither because there aren't any. I can't upgrade as it will ruin my backend totally. Do you have any idea how can I do it?
