Google map in MediaWiki not showing

Question

I have upgraded MediaWiki from 1.9.3 to 1.16.1 in a new server. However, the google map is not showing in the link. It's a blank in that page but in the old server with old version it is working fine. I am not a developer so I have no clue on this. Please let me know anybody have any idea on this. you can have a look on the below links

Answer 1

1. Was the extension re-installed with your upgrade?

2. Can you confirm that the extension you were using is compatible with the version of MediaWiki you are using?

3. Did you change the LocalSettings.php file? (i.e. does the extension rely upon any configuration settings like $wgRawHTML ..?)
