 * With compatibility mode on (i’m using polylang), the plugin does not include 
   a tempalte so WP falls back to single.php.
 * I’m able to hook to 404page_after_404 and do the include myself however.

 * You are right that no template is included, but it seems to depend on the theme
   if that works or not. Which theme are you using?

 * It’s a custom theme based on underscores

 * OK, I’ve quickly created a underscores based theme for testing and it works for
   me. It should not be necessary to change the template because in compatibility
   mode the post result ist filtered which happens before loading the template. 
   So maybe there’s a confilct with another plugin.
 * Just to be on the safe side I’ve added a filter for template_include. Current
   DEV version is available at [https://downloads.wordpress.org/plugin/404page.zip](https://downloads.wordpress.org/plugin/404page.zip).
   Would you please test it?
 * Compatibility mode has to be turned on manually in this version.

 * Please test it with version 2.2 and let me know if it works now.
