Recently after upgrading our site to Magento 2.3.3 Version, the guest user can't create an account after successful checkout.
I am getting the below log messages, can someone help me on this.
main.DEBUG: URI '/checkout/account/delegateCreate/'' cannot be accessed with POST method
(Magento\Checkout\Controller\Account\DelegateCreate)
Check this file in your custom template it might be the problem:
app/design/frontend/YourCompany/yourtemplate/Magento_Checkout/web/template/registration.html
You may need to compare and replace the contents with that in the magento distribution:
vendor/magento/module-checkout/view/frontend/web/template/registration.html
for example;
<div>
<!-- ko if: isFormVisible -->
<p data-bind="i18n: 'You can track your order status by creating an account.'"></p>
<p><span data-bind="i18n: 'Email Address'"></span>: <span data-bind="text: getEmailAddress()"></span></p>
<a class="action primary" data-bind="attr: { href: getUrl() }">
<span class="btn btn-default" data-bind="i18n: 'Create an Account'" />
</a>
<!--/ko-->
