Dupe the folder giving it a new name. Give these files a new name:
cmap.min.css cmap.min.js cmap.php
cmap.php and change every reference to cmap to something else. Make sure the reference to the css/js file names match whatever you renamed the files as.
After you’ve done that, you should be able to safely Active the plugin and it should show up as template option on the Connections : Templates admin page.
