For me,data loss,
Lost-Many visitors messages.(Also deleted visitors messages reappeared back) (I know this is "normal" do the server restore).
Lost-All the reputation received.
Lost-These cases are missing,i know that because i bookmark few of my cases for faster reply.
I think that's it.
Well,not a really problem here.
And many of posts\replys,
Example this case is solved,is missing the part...
panais ""so far so good
loaba ""the program is working perfect thanks""
panais ""you are welcome,if you need anything else you are always welcome to ask if not then remember to mark the case as solved
And he marked the case as solved.
And again not a really problem,few hours "work" and everything will come back to normal.
