Firstly great plugin!!
I am having a couple of issues though..
First - When I login I get the message below at the top of the screen..
Error: HTTP Error:22/The requested URL returned error: 404 at https://mysite.com/clients/dologin.php?systpl=portal
The account is logged in but you only know this once you click to somewhere else..
Second - There is a error showing on the config page..
Warning: Invalid argument supplied for foreach() in /home/mysite/public_html/wp-content/plugins/whmcs-bridge/support-us.inc.php on line 46
The error is showing between the "If you like this plugin" box and the Zingiri logo..
