If after theme installation you have white screen, please check the following:

Enable wp-debug and set to true: https://codex.wordpress.org/WP_DEBUG

If you see this error:

Parse error: syntax error, unexpected T_FUNCTION in /wp-content/themes/wpresidence/libs/3rdparty.php on line 266

This means your server PHP is older than 5.3. Please ask hosting to upgrade your PHP to at least 5.6 for best performance.
