WHMCS WP Integration Plugin Not working

Hi, I am getting an error using the WHMCS WP Integration plugin that says: Sorry this doesn’t look like a WHMCS site at http://www.wordpressforpi.com/client/ Make sure your WHMCS Integration settings are pointing to the correct URL and that the WHMCS site is set for the Portal template in Setup | General. http://wordpressforpi.com/whmcs-test/

My settings are correct per your instructions
