Please be informed that you should not upload the whole item you have downloaded from ThemeForest as you will get an error message. Instead:

1. Download the Theme archive and extract the main theme zip file with the title (noor.zip)
2. You may need to preserve the folder structure in the archive when extracting these files.
3. Use an FTP client (for example Filezilla) to access your host web server
4. Transfer your unzipped theme to your server in the wp-content/themes
5. Once the theme is uploaded, you need to activate it. Go to Appearance > Themes and activate your uploaded theme.
