looks like the Plugin is not authorised to use your GMail account.
In the past you could disable the plugin and reactivate it and it asked for authorization. But you may want to ask for support with the plugin author.
Thanks for your reply. I deactivated and then re-activated the WP Mail SMTP plugin. I then unauthorised and tried to re-authorise but I got this message:
It was pure fluke what I did – I have no idea! ha ha.
I re-set the secret. I then removed the authorisated re-direct URL and re-copied and paste from WP and saved settings. It then let me proceed to go through the authorisation successfully in WP Mail SMTP.
At least I know what to do if it happens again (if I remember) π
Haha – thanks for sharing.
