Hello @Sharpy01,
The PHP Error is this:
Fatal error: Uncaught Error: Call to undefined function print_attribute_radio() in /home/189110.cloudwaysapps.com/pnxrscvvut/public_html/wp-content/themes/pro-child/woocommerce/single-product/add-to-cart/variable.php:62 Stack trace: #0 /home/189110.cloudwaysapps.com/pnxrscvvut/public_html/wp-content/plugins/woocommerce/includes/wc-core-functions.php(251): include() #1 /home/189110.cloudwaysapps.com/pnxrscvvut/public_html/wp-content/plugins/woocommerce/includes/wc-template-functions.php(1630): wc_get_template('single-product/...', Array) #2 /home/189110.cloudwaysapps.com/pnxrscvvut/public_html/wp-includes/class-wp-hook.php(287): woocommerce_variable_add_to_cart('') #3 /home/189110.cloudwaysapps.com/pnxrscvvut/public_html/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters('', Array) #4 /home/189110.cloudwaysapps.com/pnxrscvvut/public_html/wp-includes/plugin.php(478): WP_Hook->do_action(Array) #5 /home/189110.cloudwaysapps.com/pnxrscvvut/public_html/wp-content/plugins/woocommerce/includes/wc-template-functions.php(15 in /home/189110.cloudwaysapps.com/pnxrscvvut/public_html/wp-content/themes/pro-child/woocommerce/single-product/add-to-cart/variable.php on line 62
This means that in the line 62 of the file: woocommerce/single-product/add-to-cart/variable.php, there is a missing function:
<?php

This means that your custom code added in your child theme has some errors. You are using the old version of the template. In the latest version of WooCommerce, the code which should be added for the variable.php file will be:
<?php
/**
* Variable product add to cart
*
* This template can be overridden by copying it to yourtheme/woocommerce/single-product/add-to-cart/variable.php.
*
* HOWEVER, on occasion WooCommerce will need to update template files and you
* (the theme developer) will need to copy the new files to your theme to
* maintain compatibility. We try to do this as little as possible, but it does
* happen. When this occurs the version of the template file will be bumped and
* the readme will list any important changes.
