안녕하세요

오늘 홈페이지 관리메뉴에 접속하니

EMAIL DELIVERY ERROR: the plugin WP Mail SMTP v2.2.1 logged this error during the last time it tried to send an email:

Mailer: Gmail
{
"error": "invalid_grant",
"error_description": "Token has been expired or revoked."
}
Please re-grant Google app permissions!
Go to WP Mail SMTP plugin settings page. Click the “Remove Connection” button.
Then click the “Allow plugin to send emails using your Google account” button and re-enable access.

Consider running an email test after fixing it.

라고 뜨네요

안내에 나온 대로 'Remove Connection' 버튼 누른 다음에 'Allow plugin to send emails using your Google account' 버튼 다시 누르고 저장했는데.

에러 메시지가 사라지지 않습니다

무엇이 문제일까요
