Database write failed.
Been wanting to 'Like' and tried to comment on people's posts, but this message keep appearing and I failed to do both.
I also could not update my facebook status and unable to upload any photos to my account.
Been having this problem since last night, but I thought that it was just temporary and will go away on the next day. But I was wrong as I'm still facing with the same problem today.
Reported this to facebook help center.
This never happens to me before and so I thought maybe I did something wrong, as in published some offensive materials or someone reported me as being 'annoying' to facebook. And I googled about this matter for a better insight of the problem and it turned out that I'm not alone in this world. ;p
Others is having the same problem too.
Dear facebook, please get well soon. I want to hit the Like button so badly. :)
*Updated!* on 29/5
No more FB problem! It was cured yesterday night. :)
