Oops something went wrong. Invalid send method

[lddd]

Hello there,

I always end up with this error message on the front end of my contact page.

It says: Oops something went wrong. Invalid send method*

The test connection on the backend under settings for WP-MAIL works and the message gets delivered. But somehow if filling out the regular form on the website and trying to send it it always keeps pushing this error message and the message also won´t be delivered.

I also tried SMTP by using my Gmail Account but its not working as well. I just get the error

AJAX error: SyntaxError: Unexpected number in JSON at position 4

How to further debug this why its not working for WP-MAIL and even SMTP?

thanks in advance

I solved it once usually its a server issue but I don't remember how I solved it: ThemeFuse/Unyson#3172

Sorry but i can´t give out any credentials. The website is not in production yet.
I could not find any server issue with sending mails, all other SMTP Plugins are working as well.

I mean for the WP-MAIL method test mails are working but i don´t understand why its then displays this error message on the front-end... Really strange.
