Advanced Form Designer Changes not saving

Hello, I made changes in the Advanced Form Designer that are not saving/ transferring to the live form.  Specifically, I changed the colors in the error and highlight states.  It was working at some point, but now it defaults to white highlight (so you can't see the text) and an ugly red error message.  The form with this issue is the Create Account Form.   PLease help!

To change the background highlight and error message, add the following CSS to the form:

.form-line-error {

    background-color: #122f44 !important;

}

.form-line-error .form-error-message {

    background-color: #000000 !important;

}

.form-line-error .form-error-message .form-error-arrow {

    border-bottom-color: #000000 !important;

}

The colors #000000 and #122f44 can be changed to those you require.

The error was due to our server and it has been fixed. Please check if you are able to save the CSS now.
