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 bellow code to the line 2 of this file: /wp-content/themes/InTravel/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);
/**
* InTravel import demo data content
*
* @package InTravel
*/
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)
