Marker Clusterer, not zooming in when clicked

Question

I'm using Marker Clusterer with all the default settings, on a map also using just default settings. The marker clusters display fine, but unlike the example in the documentation, the map does not zoom in when a cluster is clicked. The map only centers on the click on cluster but does not zoom!

Has anyone else had this problem before?

Answer 1

That setting was true thank you davidhund. I replaced the code with a different version, and the problem has vanished.
