Wordpress Integration links bring me back to WHMCS

I've got the integration plugin working to a point. The short codes work within wordpress but when I got to click a link associated with WHMCS the link takes me back to the WHMCS website. It's not staying on the wordpress site. I am using the "Portal" theme on WHMCS and the "twentythirteen" them on wordpress (also tried the twentytwelve theme).
