Blank screen

Sadly the plugin is not working for me. I just get a blank screen and nothing syncs. Im using the “page” method.
Facebook APP created and works on other plugins.

With de WP Debug on I also get some “file not found” errors;

Warning: include(includes\egany_facebook_to_wordpress-ajax.php): failed to open stream: No such file or directory in [domain path]/public_html/wp-content/plugins/egany-facebook-to-wp/egany_facebook_to_wordpress.php on line 90

I fixed the url issues, and i get the sync screen, but no posts are inserted into WP.
