Unable to Log in to the website using Ultimate Facebook connect in Google Chrome

Hi guys,

I was able to log in to the site while using google chrome, a couple of weeks ago. but when i check again today I get a error msg as below :

"Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains. "

I have checked on IE and Fire fox the log in process is working fine.

i have checked and double checked the configuration on WP and FB.

Can you please help me?

the URL is http://www.ninthmall.com

Thank you and best regards,
