[NO] CAN MODIFY / CHANGE THE MAIN PRODUCT means NO
You can only sell the main product AS IS… any other modifications can be seen as
a breach of license in most, if not all cases.
It is my advice, when you see these terms, to leave the product alone, and only sell as it comes.
There is more than enough PLR out there, so as to not get ones self in trouble.
