Why does the “activate” message not appear when an account is registered?

Thanks Conor 🙂

I’m not sure exactly why it gets hidden for some users. Maybe it’s related to the theme or some other plugin getting in the way.

If display: block !important is not enough for displaying it, please try to also use visibility: visible;

In the end it would be something like this:

.woocommerce-error {
    display: block !important;
    visibility: visible !important;
}
