On uploading the theme to wordpress I get the error:
The package could not be installed. The style.css stylesheet doesn’t contain a valid theme header.

Hi there,
Thanks for reaching out.
In relation to your query here, it sounds as if you are uploading the wrong zip file. Could you please extract your theme files and upload the zip file with the root theme files. Else, you can also try uploading the theme files via FTP.

I hope this helps.
Best Regards,

I am having the same issue. I have tried exacting the file but get the same results.

Hi there

All our WordPress themes can be installed from appearance > themes > and you have to use install the theme, then from the WordPress repository, you can install themes by searching them. most probably you are guys uploading one of our HTML templates which cannot be installed in the WordPress as a theme
