1.3 Install Demo Data

At first, you will have to check some of your server configurations with your host. The Recommended PHP Configuration Limits should be paid attention. In several cases, you may deal with problems related to low PHP configuration limits, such as white screen, demo content fails when importing, empty page content and other similar issues.
The solution is to increase the PHP limits. You can do this on your own by editing the following lines in the php.ini file in your root directory. This is not a file that comes with WordPress so if you are unfamiliar with it you should contact your web host about increasing those limits to a minimum as follows:
You are running WordPress 4.7 or higher
Your PHP version should be 7.0 or higher 
max_execution_time 360
memory_limit 128M
post_max_size 32M
upload_max_filesize 32M
If your server configurations on your side will right, please follow next steps:
1. In your WordPress dashboard, go to Appearance > Themes > Add New.
