I just tried to install this to see how it worked and got the message – The package could not be installed. The theme is missing the style.css stylesheet.
I tried to download again, in case I had an older version. Same result.
You are facing the issue as you are uploading the incorrect zip.
You don’t have to directly upload the zip file which you have downloaded.
1. First, Extract the downloaded hotoven.zip file.
2. You will find the “Demo Data” folder and the “Theme” folder in it. Open this “Theme folder”.
3. Here you will find the actual installation zip file i.e hot-oven.zip. Please upload this zip file while installation.
