Now plugin does not work !!!

I have exactly same issues as above, even using the same ISP. My message error is:

And actually, clicking on “next” button doesn’t advance further in settings steps. Any idea on how to solve this?

🙂 You’re right I should be a pro by now, but I took it was working fine on its own so I never checked its health status. Only now I discover it doesn’t work. But the problem is that I have no error message, i.e. the setings seem stuck (“next” button does not activate). This looks like that Javascript issue I had once, but this time even using the manual configuration doesn’t seem to activate the “next” buttons.
I have tried with another SMTP plugin and it works, but I’d rather stay with Postman which I’ve reinstalled from scratch…. but the problem stays.

I was hoping you ask to take a look inside. Please log in here, I created Jason + smtpass login details for you. The site is in Italian but I’m sure you’ll find your way around.

so, since the problem has got an old solution I took that solution and now it works (I just copied the code that somehow wasn’t there anymore, and put it into function.php).
I don’t understand why developers don’t follow standards. Too many plugin conflicts are out there, and there never is a workaround. Fortunately there was one for Postman. Thank you.
