Castling problem....

Hello everybody!

Maybe I'm missing something but in on of my games, the system does not allow me to castle....

It's very strange because I conform to all the points which makes it possible to castle, i.e.:

1. The king and the chosen rook are on the player's first rank.
2. Neither the king nor the chosen rook has previously moved.
3. There are no pieces between the king and the chosen rook.
4. The king is not currently in check.
5. The king does not pass through a square that is attacked by an enemy piece.
6. The king does not end up in check. (True of any legal move.)

My question to chess.com is "Why can't I castle here?"

Thanks to those who might enlighten me !

Yes I did it all correctly. I'm on chess.com since 2010... ))

Oh! That's OK now... strange, but at the end it worked!
