I’m trying to add a third party shipping plugin (canada Post). I access it from woo-commerce/shipping, it redirects me to the third party where i have to put in my credentials after i do it redirects me back to my website and I get a 404 error. When i get to this page i’m not able to access my dashboard and can only toogle through pages on the site. when check the status of woocommerce it shows an element is outdated.

loja/woocommerce/single-product/add-to-cart/grouped.php version 4.0.0 is out of date. The core version is 4.8.0,

Can you help fix this problem
