To access it you have to navigate to the PixiePanel / Routes / Routes settings
Admin Panel → PixiePanel → Routes → Routes settings
Here you can edit the available theme routes. Changing this information means that you will change a prefix for the url.
Example of a change is: http://themes.pixiesquad.com/match/92
That changes to: http://themes.pixiesquad.com/id/92
What we did here is changed the prefix for the match route from: “match” to “id”.
