Firstly go to Theme Options > Import Demo, press Import demo content button to install products, categories, posts, portfolios, some pages, widgets, menus.
If you get an internal server error or blank page when importing please try appending below code to the line 2 of this file: /wp-content/themes/lightbook/framework/importer/importer.php
ini_set(‘max_execution_time’, 900);
ini_set(‘memory_limit’, ’64M’);
ini_set(‘max_input_time’, 0);
Here is the result:
<?php
ini_set(‘max_execution_time’, 900);
ini_set(‘memory_limit’, ’64M’);
ini_set(‘max_input_time’, 0);
/**
* lightbook import demo data content
*
* @package lightbook
*/
And then click button “import demo content” again.
If your site has duplicate content, try to reset all using this plugin and then import demo data again: https://wordpress.org/plugins/wordpress-reset/
You should empty the upload folder too (wp-content/uploads)
