All depends on which one you are using - you are using the free plugin, so you go to the Plugins listing and edit the setting right here:
This is a confusing one - the hook to load your configuration content is displaying the default value of the final settings for the configuration, which is an empty JSON array:
<script type="text/javascript"> var $buoop = [];.....
But your 'Other' tab content which you sent to me shows that the content is being created by the application - and therefore should be getting loaded in that hook.
If possible, can you throw me ACP login details for your site so I can have a look at the settings a little closer?
