How to fix redirect and appearance issues on a login page?

Topic summary

A store’s login page is experiencing two main issues:

Visual Problems:

  • Input fields display with transparent backgrounds instead of white
  • Email field is missing its border

Critical Redirect Issue:

  • The “Register Account” button redirects to a blank page showing only a “Login” heading
  • However, opening the same link in a new tab correctly loads the account registration form

The user has shared three screenshots showing these problems and included their login page code (appears to be a Liquid template for Customers/Login). They are seeking help to resolve both the styling issues and the redirect malfunction.

Hello, I have been attempting to fix a stores login page with some success but the input fields are now transparent (instead of white background) and the email field has no border. Most importantly the register account button redirects to a black page with the heading “Login”, but if I click “open link in new tab” it takes me to the correct account registration form. This is the code for the login page if anyone can help I would appreciate it:

Customers/Login.liquid
