PHP致命错误：phpmailerException未捕获：SMTP错误：无法验证

Question

我已经开始投票了，我是PHP的菜鸟，我了解不多。

我无法登录或经过发送到我的电子邮件的验证页链接。我已经检查了不赞成使用的文件，但显然已经进行了更改。它从来没有这样表现过，下面是我的public_html文件夹中的错误日志

这是class.phpmailer.php的一部分，应该有一个错误。

    }
            if ($this->SMTPAuth) {
                if (!$this->smtp->authenticate(
                    $this->Username,
                    $this->Password,
                    $this->AuthType,
                    $this->Realm,
                    $this->Workstation
                )
                ) {
                    throw new phpmailerException($this->lang('authenticate'));
                }
            }
            return true;
        } catch (phpmailerException $exc) {
            $lastexception = $exc;
            $this->edebug($exc->getMessage());
            // We must have connected, but then failed TLS or Auth, so close connection nicely
            $this->smtp->quit();
        }
    }

当SMTP验证失败时，会发生这种情况。如果已配置有效条目，请检查配置。
