Hi there and welcome!
You're not supposed to enable the plugin (the community version just does not have the additional code). Instead:
- download the normal version from the Download
- install in your WordPress site the downloaded zip
From there you will have full functionality. You should then enter your update code in the corresponding configuration field to allow one-click updates through the normal WordPress update process.
Here are the documentation on Installing weeblrAMP
and on this page you'll find the documentation on entering update code and updating
