I just installed and activated the AWS S3 add-on for WPFM-Pro. After setting up an S3 bucket and an IAM API Access user with S3-Full-Access rights (public disabled), I put the settings in the WPFM S3 settings tab. But when I try to login to the front-end I can no longer upload files. I get a server error message popup from the plug-in. Here are my WPFM S3 settings:
Enable AWS S3: Yes
API Key: (my IAM S3 user Access Key)
API Secret: (my IAM S3 user Secret Key)
Bucket name: transformedstyle-fileupload-wp-plugin
URL Expiration: 5
Region Name: us-east-1
Permissions Public? No
