From v2.4 on, you have to specify each field you want to have returned from the Grpah API. You should be able to use
/elbeko/feed?fields=id,message,link,attachments{media}&limit=25
which returns something like
{
"data": [
{
"id": "1472127519670095_1645415342341311",
"message": "Benieuwd naar ons nieuw project in de regio Gent? Binnenkort meer info via www.elbeko.be!",

In the past, responses from Graph API calls returned a set of default fields. In order to reduce payload size and improve latency on mobile networks we have reduced the number of default fields returned for most Graph API calls. In v2.4 you will need to declaratively list the response fields for your calls.
