Facebook Login Not Working After changing new App_id and App_secret

Hi Alex,

I am facing problem on my website www.emazeme.com/ in which facebook login is working from last 6 months with the help of JFBConnect 4.2.2
And now i have created my own application on Facebook so i updated the new App id and app secret , then Facebook connect is not working. I Have also shifted my website from 1and1 hosting server to Bluehost hosting server. I have attached the an image which shows the error while doing autotune in JFBConnect.

And other information i wanna give you is JFBConnect is recommending canvas url as same as the site url but my canvas url is different which is the path of folder in which app files are placed.
My Fb App url is :- www.emazeme.com/facebook/examples/
JFBConnect Recommends :- www.emazeme.com/

So do i have to use 2 different apps one for website login and other for by Facebook Application. Or is their any document regarding this that you can suggest from where i can find solution for this thing.
Regards,
Ashok
