If you are are receiving a 404 error on obituaries then you may need to save permalinks. Navigate to the permalinks page and click save. This rewrites the permalink structure and will fix your 404 issue. If that did not fix your issue please make sure you are not running the obituary shortcode on the home page. Running the obituary shortcode on the homepage will cause errors, you can create a page for obituaries and then use the latest_obits shortcode to display the obituaries on the home page.
