It’s a Chrome 59.0.3071.109. I was looking for a problem for a couple of hours. First step form submit is seting up cookies but doesn’t redirect to second step. Submiting second step form send an email correctly. While I disable the plugin both form sends an email after submit.
I tried to force first step to redirect to second with:
$("#first-step-form-id").on('wpcf7:submit', function(){
location = 'second-step-form-url';
});
but it works only with plugin disabled. If the plugin is active, nothing happen.
I can give You an access to my sample page where I’m trying to make it wark if You wish. Just send me a msg at [email protected]
