whmcs plugin installed in subdomain, wordpress installed

i have wordpress installed with your plugin. I will eventually have this wordpress site at root of domain after I built it, however for staging I have installed in subfolder with the whmcs plugin and when populating the encoded field with the correct urls in multiple formats with/no http:// with/no https:// and gives error it says invalid domain. WHMCS is installed on same domain and is currently pointed to a subdomain
