Login fail IE 7-9

Hi everybody,

When I try to login with facebook in IE. I get a blank popup window with the url referring to the URL
www.travelspecs.com/Travel-Tips/?fb_xd_f...main=travelspecs.com

and IE Error message
Message: Unable to get value of the property 'FB': object is null or undefined
Line: 12
Char: 3272
Code: 0
URI: connect.facebook.net/en_GB/all.js

Can somebody help me?

Hello there!
I have the same exact issue.
I am running a JFBConnect version 4.0.2 and Joomla version 1.5.25
It's very weird. the behaviour changes from PC to PC. How is that possible?

Regards,

Daniele

p.s.
I checked out the error.log of joomla and i found a PHP Notice: Undefined variable: return in /var/www/xxx/web/components/com_jfbconnect/libraries/facebook.php on line 159.
The problem in my opinion is related the the issue i am facing. On the front end i sometimes receive the following error message: "We were unable to retrieve your Facebook account information. Please try again". This message is thrown in loginregister.php line 121 if the validateToken return false.
ValidateToken is the function that fails because of the undefined variable "return".
Hope this help.

Regards,
Daniele
