AWS secret key changes after save & CloudFront settings page is blank

Hello,

I’m trying to use this plugin for the CloudFront CDN.

I’ve followed the setup instructions in https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/WordPressPlugIn.html#WordPressPlugin-configure-use, but every time I save my access key and secret key, the secret key shortens and the CloudFront settings page is always blank.

Please advise on how to resolve this issue.

Thank you!
