Type: SuggestionDescription: 7.4 is now the Wordpress min recommended version.It's embarrassing setting up a brand new server and the client sees the "your php is out of date" warning.
We already have WordPress images with PHP 7.4 and we have sent them to AWS, but they haven't published it yet. There's nothing we can do about that.
Images in EC2 and the AWS Marketplace already come with PHP 7.4 installed. You can check it if you are interested: https://aws.amazon.com/marketplace/pp/Bitnami-WordPress-Certified-by-Bitnami-and-Automat/B00NN8Y43U
Is there some way to contact AWS to get an updated image?
You can find a list of updated images here (https://bitnami.com/stack/wordpress/cloud/aws/amis) and you can launch them through the Amazon console.
Unfortunately regarding Lightsail we can't do anything other than wait for them to publish the new images.
