hi,
i think we misunderstood eachother or i have not undesrtood..I had the Facebook id and facebook secret as my IMGUR screen shows (above) The problem is why i clicked "generate access token " a window popped up (facebook) where i had to log in ...It is when i clicked insert and save button that the data was not inserted...
anyway i did try waht you said (to be on the safe side) and now when i try to regenerat etoken i get the following error...Invalid app ID: The provided app ID does not look like a valid app ID.
which in my opinion makes sense...
