Security token was missing or Invalid forum specified - vBulletin Facebook App

[farhanisfarhan]

Hi there,

My app on: https://apps.facebook.com/muslimforum/
gives this error if I am not logged on:
Invalid Forum specified. If you followed a valid link, please notify the administrator

My app following the link through facebook menu on: https://apps.facebook.com/muslimforu...0&fb_bmpos=3_0
gives this error if I am already logged on to facebook:
Your submission could not be processed because a security token was missing.

My app was working perfectly for long but recently after upgrade to 4.2.0 patch 2, I noticed that it is giving the above mentioned errors.

Anyone can suggest anything ? Thanks in advance

When I go to your app I see your forums rather than the app - this means your URLs are wrong either in:

- the app config.php file or
- the Facebook Developers site

Go back through them all in line with the instructions linked below and make sure you have them correct:
