ERROR: Password Fields are empty

Password field is empty, but it really isn’t

We were currently working on a website and suddenly we couldn’t login to the WordPress admin of our site. We kept receiving the error message “Passwords fields are empty”. However, the password field wasn’t empty. We searched for online solutions and finally found one that solved are problem. We simply had to delete white space at the bottom of our wp-config.php file and we were able to login.
