It has already happened to me on a few occasions: when I complete a form and test it, if I leave a required field empty, the notification correctly indicates the missing field.
The problem arises when I try to submit the same form again after that — it doesn’t go through.
Please contact your web host to ask them to retrieve the stack trace for the critical/fatal error from the site/server logs
That file hasn’t been updated since May. You might have error logging disabled, or they are being recorded elsewhere.
I have enabled Gravity Forms logging and tried to reproduce the error. It only occurs with an email field, which, when filled out incorrectly and then corrected before submitting the form, triggers a critical error on the site.
