As you can see from the pictures, the login page WPLMS has black background and white letters.
The bug appears when a wrong login is introduced. THE WP redirects the student to the default page wp-login.php and the problem, as shown in the images, the letter remains in white.
It makes it very difficult and confusing registering because it does not seem be writing the student.
It is a failure, for me, big. I would like to be resolved soon
(In the picture I have selected the text so that you can see that there are letters because the background is white)
Please try adding the following css in your wp-admin->wplms->miscellaneous->custom css for wp login screen:
.login form .input, .login input[type=text] {
color: #444;
}
Let me know if this helps.
