When I upload the theme file i receive the error in attach.
Attached files: ErrorPAtti.jpg
This means that the theme file is bigger than the maximum upload file size limit. You can check this in Media->Add New: http://prntscr.com/g3xobz
The theme has approx 15MB.
What you could do is to increase the maximum upload file limit to at least 20MB. If you don`t know how to do it, please ask your webhosting provider and they will do it in no time. If your webhosting provider is a reliable one, you should be able to get support via live chat.
Let me know how it goes!
