All output should be run through an escaping function (see the Security sections in the WordPress Developer Handbooks), found '__'.

Tested up to: 4.9 < 6.8. The "Tested up to" value in your plugin is not set to the current version of WordPress. This means your plugin will not show up in searches, as we require plugins to be compatible and documented as tested up to the most recent version of WordPress.

Mismatched Stable Tag: 1.2 != 1.3.0. Your Stable Tag is meant to be the stable version of your plugin and it needs to be exactly the same with the Version in your main plugin file's header. Any mismatch can prevent users from downloading the correct plugin files from WordPress.org.

Mismatched Requires at least: 4.0 != 4.5. "Requires at least" needs to be exactly the same with that in your main plugin file's header.
