Contact Form 7 does not show success message

Hi Minti team,

We’re running into an issue with CF7 not showing a success message after a form has been successfully sent. Without a success message, there is no way for our client’s customers to know that their message got through. I found this code snippet and added it to the custom CSS, but that does not seem to solve the issue:

.wpcf7 span.wpcf7-not-valid-tip, .wpcf7-validation-errors{ display: inherit !important; }
.wpcf7-not-valid{ border-color: #ff0000 !important;}
.wpcf7-validation-errors {background: #ff0000 !important;}

It would be great if you would be able to let me know how to have the message appear. Thank you in advance!
