SMTP Error: Could not authenticate.

Gmail phpmailer will prompt error like this normally when you changed the running script from one server o another. Even the Gmail account login credentials are correct, Google’s servers may still block the new server to authenticate.

To get this resolve, please log in using the same Gmail account in your browser, and then open the link below and go through the verification process:

This will authenticate a new server for your Gmail account. Kindly try to authenticate using the phpmailer again within 10 minutes.
