Editor: elementor

Theme: manufacturer from Theme forest

You may experience a blank page, which is not the home page, and I found it is the due to theme to woocommerce integiration.

Turned on the Use the option switch front-end editor loader method. 

You can find it in the settings of Elementor in your WordPress Dashboard (see the screenshot below). Enable this option and check if it solved the issue. Go to Elementor > Settings > Advanced

Uncaught Error: Call to undefined function is_shop() in /public_html/wp-content/themes/manufacturer/header.php:288
Stack trace:
#0 /public_html/wp-includes/template.php(730): require_once()

Find the file /public_html/wp-content/themes/manufacturer/header.php

Go to line 288, you may see a condition code like below:

if(is_shop()) {
$shop_page_id = (int)get_option( 'woocommerce_shop_page_id' );
$hide_title = get_post_meta($shop_page_id, 'hide_title', true);
}

 

Well, the function is trying to see if current page is a shop page, then get the theme option and apply. Some developer may developing a website without woocommerce, so this issue happened.

The solution will be:

1. Use woocommerce: Install Woocommerce and activate, this issue will automatically be fixed.
2. Website without woocommerce: Simply delete the if condition code in 288 will fix this.
