Success messages not showing up

Hi.

I’m using your plugin here: https://loja.fresenius-kabi.pt/recover/
The mechanic is working fine: It sends the email with the correct link and I change the password and it takes effect.
The problem is that there’s no success message on submit the email and when setting new password. But the incorrect email message is returning fine: https://prntscr.com/105uoy0

Any guess?

Thanks,
Andre
