I dont know why, but sometimes
thumbnail does not appear when i post on fb, i see only post (text) without image
Even if i try once again (right now i try even 5 times with the same post) its the same situation
Another problem when trying to click Recomend on link that has a thumbnail image on the FB. I click Recomend on my www, but i dont have thumbnail image,only text.
It does not happen that every time, but it is very persistent
