WHMCS Wordpress Integration 1.2.1.8 + nginx

Hi, I hope that you can help me.
my site is setup with whmcs at http://andersjakobsson.com/hosting/
created a page with [wcp_content] http://andersjakobsson.com/portal/

but no links is working, is this a nginx rewrite thing? have searched for help but no luck.

Best regards, Anders
