I am testing the plugin on a local Xampp setup of WordPress.
When I goto my comments area reply box, click on the link in "You can manage the subscriptions of this post" it takes me to this URL: http://localhost/http://localhost/?page_id=9999999/
and it says:
You don't have permission to access the requested directory. There is either no index document or the directory is read-protected.
If you think this is a server error, please contact the webmaster.
Apache/2.2.21 (Win32) mod_ssl/2.2.21 OpenSSL/1.0.0e PHP/5.3.8 mod_perl/2.0.4 Perl/v5.10.1
Is there something I am doing wrong?
