[Answered ]-Problem with i18n urls where I'm redirected to the right url but the template is not found

If your simple HttpResponse('Hi') works but your Response with the rendered template is not, this has nothing to do with your i18n prefixed URLs but with the loading of the template.

Make sure the template actually exists in PROJECT_ROOT/sitepages/templates/sitepages/news_events_page_listing.html' and sitepages is listed in your INSTALLED_APPS.

As an alternative, you could move the template to any app you’ve listed in your INSTALLED_APPS and make sure the path, starting from the templates/ directory of that app, matches the template name you use in your view.
