You can find more information on how to import the demo content here: How-to-upload-dummy-content
Note 2 things:
1. Images on demo are copyrighted and you cannot use them without purchasing proper licenses. Ideally you must refuse importing media files during content installation. So we are not responsible for any possible copyright infringement.
2. Demo will only import contents, will not include widget settings or menus. You will need to configure them manually.
Also you will need to set home page in settings > reading, import theme settings, sliders if needed.
If you cannot import demo content please make sure that your php.ini settings are not less than:
max_execution_time = 60
memory_limit = 256M
post_max_size = 64M
upload_max_filesize = 64M
You can contact your hosting company for more details and assistance on it.
In case you face difficulty to import demo you can download and try this part by part package.
