error with events plugin on my site

Hello Sir,

I am trying to understand use of the plugin called Events+.

Do we need to install google map plugin with events+ plugin or, not?

I am not having option to add exact address in the map in the events post writing.

And map is not displayed on the events page.

Beside this I am getting following error at my page:

I am looking for your help. Thanks.
