LoginRadius and SimpleModal Login

Thanks for the nice plugin.

I want to have LoginRadius in popup winddow so I have installed SimpleModal Login plugin.
As explained on the topic ‘http://wordpress.org/support/topic/no-buttons-when-combined-with-simple-modal-login-plugin’, I have put the code you suggested and it shows the SNS icons successfully.
However when any of SNS icon clicked, I’ve got error message like this,

“
For security purposes, the host of the URL which is passed should be the same as the one used to generate the LoginRadius API Key and Secret.
To correct this, add the LoginRadius widget on the same website you entered in your LoginRadius user account
“

Without SimpleModal it works fine but I really want this SimpleModal plugin together with LoginRadius.
Please help.
