Problems configuring SMTP

Hi, i have this problem when i try to setup SMTP service.

How should i solve this?

Hi cleuncuyo, this is unusual. Anytime the “Oh no” message comes up it means there has been a PHP error of some kind. The error itself isn’t displayed on screen for security reasons. Can you check the PHP error log on your server and look for an error related to the System Admin module (or around the same time). The info in the error logs should give some clues as to what the issue may be.
