I want to add phone number to the customer creation page, since on of our users want's to contact people when they register to their webpage.
I did follow this guide (https://store.magenest.com/blog/add-custom-field-to-registration-page-magento-2/) But as you can see (http://lommel.no/customer/account/create/) no phone number was added.
I did upgrade - dicompile - content:deploy - reindex and cleared cache. But nothing.
is there something wrong with the guide?
Magento version: 2.3 Theme: Porto
Any help is appreciated
