That error message means that some plugin has hooked into the deprecated contextual_help filter.

To find out which plugin it is, deactivate all of your plugins and then reactivate them one-by-one until you see the error message again.

Thank you! After de/re-activating plugins, that message disappears. Looks like some glitch during WP upgrade.

Replying to pbiron:
