Gentlemen, do not buy such products. don't waste your money. The systems they sell are broken and not problems that the average software developer can fix. In short, these are scammers. I know a little about the people who do it and how it's done. For example, it says gblicensev10, photos gblicensev6 only belong to cpanelv3 gblicensev10, it also has chronic problems, for example cpsvrd closes webmail ports. The cpsvrd file is the one that makes the licensing system and an elf file is not worth the hassle, it will only cost you a few thousand dollars to clear these files. They sell for 300-500 dollars, so don't believe it, they are scammers, don't believe those who sell it. usually bangladesians sell it. stay away from them
