Thank you! Maybe there was a confusion , I do not speak good English, I do not want to delete credit from the source code and distribute it, I want to remove links to CubeCart in the visual part ( footer , login , admin footer , logos, etc. ) and I want to sell online stores in subdomains. The licence say: Permitted Commercial Use Distribution Modification Patent Grant Private UseI understand I can do this. But if you say no, I understand, I appreciate your time and I'll leave it.
