Mail sending only works on Test

My mail is only sent on the Mail Test, which I configured for using OTHER SMTP through gmail. In fact I receive my Test Mail, but when I try to use “wp_mail” function, it won’t sent. I’ve debugged and what is shown is below.

What may be happening? I’m calling “wp_mail” function like this:

wp_mail( '[email protected]', 'Test', 'test' );

    [errors] => Array
        (
            [wp_mail_failed] => Array
                (
                    [0] => Could not instantiate mail function.
                )

        )

        (

                (

                        (
                            [0] => [email protected]
                        )

                    [subject] => Test
                    [message] => test
                    [headers] => Array
                        (
                        )

                    [attachments] => Array
                        (
                        )

                    [phpmailer_exception_code] => 2
                )

        )

)
