Login is loading and loading and loading

Hi, This topic has been discussed here before: https://wordpress.org/support/topic/users-experiencing-issues-with-login-stuck-in-loop/

But it still doesn’t work. We use the verification link. When you click on it, you are taken back to the original page you visited (although we specified in the backend that you should go to the account page), where you are then supposed to log in and the page loads and loads and loads and doesn’t stop. If you then reload the page in the browser, you are logged in. We’ve tried all sorts of things and have now had to remove this option with the verification email so that we can use the system properly. Is there still something we can do, e.g. put it somewhere in this login file that it should refresh the page? Thank you.
