From you description it sounds like you may have not activated the template to be used on the Connections : Templates admin page…
When you first install cMap as a plugin and activating it, this just registers it with WordPress. After you activate on the PLugins admin page you then need to go to the Connections : Templates admin page and activate it on that page. This activation tells Connections to use this particular template from the many available.
Hope that clears up any confusion on activating a template.
Now, the shortcode…
You do not need to add the default options. You only need to add them to change the default. So, your shortcode only needs to be:
If you’ve been copy/pasting the shortcode and its options from the web page into the WordPress Visual editor tab, you will need to delete it and manually type it in by hand. Why? When you copy/paste from a webpage into the WordPress Visual editor you also paste the underlying HTML. This HTML when mixed with the shortcode will break the ability of WordPress to properly parse the shortcode correctly. If you want to copy/paste always do it in while the Text tab is selected in the WordPress editor. This is not a defect with Connections, not a defect at all actually it is just the way the WordPress editor works.
Hope that helps!
