问题
I am using the AWS SDK for PHP to send email via SES. I have a PHP file that i use to send email. When i use the AWS Command Line Interface (AWS CLI) to run this file I can send email. However, when i try it from the browser I get a http 500 error. Please can someone advise?
I am getting the following trace: The 'autoload.php' file is not located in the /html folder. How can I allow this to be opened? This file has read access opened for the public.
Fatal error: Uncaught Aws\Exception\CredentialsException: Error retrieving credentials from the instance profile metadata server.
