I have tried troubleshooting based on your FAQ and still can't configure a way to make the Theme upload work.
Unpacking the package…
Installing the theme…
The package could not be installed. The theme is missing the style.css stylesheet.
Theme installation failed.
Thanks for going with Camyno! You're installing the wrong file. You need to unzip the file you downloaded from Creative Market, inside you will find the installable WordPress theme "camyno.zip". Please let me know if you need anything else.
Okay, now I got it. I didn't find the other zip folder last night. Too late!
Sorry about that, glad to help!
