WooCommerce 3 Major update template errors

Question

Last week I updated to PHP 7 and I have also updated WooCommerce to 3.0.x.

But after the update I have noticed that the extra fields I had in my user registration were not working anymore. I added those extra fields using WP-Member plugins.

When I further searched on the WooCommerce system status at the bottom of the page I found this errors

customtheme/woocommerce/cart/cart.php version 2.1.0 is out of date. The core version is 3.0.0, customtheme/woocommerce/checkout/form-checkout.php version 2.0.0 is out of date. The core version is 2.3.0, customtheme/woocommerce/checkout/review-order.php version 2.1.8 is out of date. The core version is 2.3.0, customtheme/woocommerce/checkout/thankyou.php version 2.2.0 is out of date. The core version is 3.0.0, customtheme/woocommerce/content-product.php version 1.6.4 is out of date. The core version is 3.0.0, customtheme/woocommerce/loop/loop-start.php, customtheme/woocommerce/loop/pagination.php, customtheme/woocommerce/myaccount/form-edit-address.php version 2.1.0 is out of date. The core version is 2.6.0, customtheme/woocommerce/single-product/add-to-cart/variable.php version 2.1.0 is out of date. The core version is 2.5.0, customtheme/woocommerce/single-product/product-image.php version 2.0.14 is out of date. The core version is 3.0.0, customtheme/woocommerce/single-product/product-thumbnails.php version 2.0.3 is out of date. The core version is 3.0.0, customtheme/woocommerce/single-product/short-description.php, customtheme/woocommerce/single-product/tabs/description.php, customtheme/woocommerce/single-product/title.php

Could anyone help me fixing these and make my user registration page to appear with all my custom fields

Thanks

WooCommerce 3.0+ is a really major update and is much more strict than before. A lot of things have changed and most of custom code used for WooCommerce version 2.6+ will need to be updated.

See the related articles to WooCommerce Development blog

Here in your case you need to update all woocommerce templates in your theme located in your customtheme (folder) > woocommerce (sub folder).

To do that, you will have to replace all listed files from the woocommerce plugin "templates" folder to your theme woocommerce (sub folder):

woocommerce/templates/cart/cart.php                             => customtheme/woocommerce/cart/cart.php
woocommerce/templates/checkout/form-checkout.php                => customtheme/woocommerce/checkout/form-checkout.php
woocommerce/templates/checkout/review-order.php                 => customtheme/woocommerce/checkout/review-order.php
woocommerce/templates/checkout/thankyou.php                     => customtheme/woocommerce/checkout/thankyou.php
woocommerce/templates/content-product.php                       => customtheme/woocommerce/content-product.php  
woocommerce/templates/loop/loop-start.php                       => customtheme/woocommerce/loop/loop-start.php
woocommerce/templates/loop/pagination.php                       => customtheme/woocommerce/loop/pagination.php  
woocommerce/templates/myaccount/form-edit-address.php           => customtheme/woocommerce/myaccount/form-edit-address.php  
woocommerce/templates/single-product/add-to-cart/variable.php   => customtheme/woocommerce/single-product/add-to-cart/variable.php
woocommerce/templates/single-product/product-image.php          => customtheme/woocommerce/single-product/product-image.php
woocommerce/templates/single-product/product-thumbnails.php     => customtheme/woocommerce/single-product/product-thumbnails.php
woocommerce/templates/single-product/short-description.php      => customtheme/woocommerce/single-product/short-description.php
woocommerce/templates/single-product/tabs/description.php       => customtheme/woocommerce/single-product/tabs/description.php
woocommerce/templates/single-product/title.php                  => customtheme/woocommerce/single-product/title.php

But keep a copy of that old template before, as you will need to replace in the new templates all changes that you have maid.
