In Freeform 2.5.7, checking for required fields works well only the first time I send a form. I will get the error messages as expected. But if I go back to the form and hit “Submit” once again (without changing anything), validation does not work - I see the success message.
(In this case post-data will be saved and - sometimes - E-Mails will be sent, even if some/all required fields are empty.)
This behaviour seems to be new in Freeform 2.5. If I use Freeform 2.4.2, everything works as expected.
