If you exclude the last page in the site.html_pages through exclude_true you end up violating the assumption in the for loop that the last page won't have a trailing comma. This breaks the json data that is served to the front end.

I removed the forloop.last check and instead assign a temporary variable to check for the first non-excluded page, and then add the comma before the next non-excluded entry.
