Woocommerce error ET_WC_Order::get_total() - php

Question

I'm using Woocommerce with my Wordpress theme. The website is selling services. The template developer support is dead, they say woocommerce compatibility but there is small bug I need to find the fix myself but I don't know what to do.
When the client tries to add credit to his account he selects the value and goes to next screen where woocommerce payment gateways are shown, they are listed but 'Pay' button its not there. When I look into Wordpress wp-content debug log I got this errors:

PHP Strict Standards: Declaration of ET_WC_Order::get_total() should
be compatible with WC_Abstract_Order::get_total($context = 'view')
Change the get_total() function in ET_WC_Order.php to be
public function get_total($context = 'view')
{
$orderData = $this->etOrder->get_order_data();
$total = $orderData["total"];
return $total;
}
PHP Strict Standards: Declaration of ET_WC_Package::get_sku() should
be compatible with WC_Product::get_sku($context = 'view')
Change the get_sku() function in ET_WC_Package.php to be
public function get_sku($context = 'view')
{
return $this->post->ID;
}
