I tried to install the geocode plugin, and got a message that there was a php error on line 114. I had to delete it from my site before I could do anything with the install plugins screen.

Here is line 114:

$coord = $this->get_map()->geocodeAddress($address);

The first two steps in the read me file are:

Unzip into your b2evolution plugin directory and activate it in b2evolution.

Configure your Google Maps API key in the plugin preferences. If you don't already have one, there's a link to the application page.

So I seem to be stuck on the second half of step one ("activate it in b2evolution")--and I don't seem to be at the point I need the API key yet.

Ideas what's wrong with line 114?
