Thank you for your response but, the video you posted does not help me one bit. This is what I get when I do exactly what your instruction as well as the video’s instructions provided. See below
The package could not be installed. The theme is missing the style.css stylesheet.
Theme install failed.
This seems to me to be an issue with the actual file and not me uploading. It may be helpful to many who come across this issue if you are to create a video addressing these issues on your product and not someone else’s product.theme. Just a suggestion.
