WHMCS Integration not working for me

Hi

I'm trying to configure the WHMCS integration but it's not happening for me.

I get the error

Sorry this doesn't look like a WHMCS site at [http://******.com/clientlogin/] 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.

However, that is the correct URL.

Can you check it for me please - i'll grant access now.

Thanks
Farzan
