ERROR license.plugin.core

Hi,
I had installed marvel plugin. But later I removed it.
However, it continuously gives below error in ES logs. How can I remove it completely? I am using ES 2.3.4.

You need to remove the license plugin as well.

Note that you can ask for a free license as well (if you are only using Marvel for example).

Thank you David.
