This plugin has been working fine since I installed it on all my sites a few months ago, until this last update. Now I get the following error:
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.
So I reconnect, it works for a bit, then it stops again with this error.
