style.css error; Theme purchased from CSSigniter

Sometimes the zip file you want to upload, is contained within the original zip file you download. Try unzipping the file locally, and see if there is another zip file within.

Are you trying to upload here?
https://ww.wp.xz.cn/themes/upload/

If so, that is the wrong place. You need to login to your own site, click on Appearance, Themes, and then Add New.

You may want to start by just creating a site at wordpress.com

Note, wordpress.com is not the same as ww.wp.xz.cn

Hi there,
this is Anastis from CSSIgniter.

These forums are not meant to provide support for premium themes such as ours. The most appropriate place to ask such questions would be on our support forum, over at http://www.cssigniter.com/support/

Now, in order to install any theme, you need to have a self-hosted WordPress installation. Once you have that, a step by step guide on installing a theme can be found here: http://www.cssigniter.com/docs/article/installing-a-theme/

Please note that our themes do not work with wordpress.com, only with self-hosted installations, i.e. the software downloaded from wordpress.org

Please direct any further questions to our support forum.
