I have JFB connect installed in many websites and everything works fine. Last days when i setup JFB connect exactly with the same settings like other websites and create facebook app with exactly same settings as for all apps i noticed that when i click on login it shows me the facebook connect window but when it only pop ups a white window and nothing happens!
On all other websites everything works fine! I noticed that only for the apps i created last month.
What should i do? Your help is very importand for me.
