Unable to post item to the auction house... this has happened before

Surprised nobody has posted this, a lot of items, like cubes of augmentation, lions hides, and just various other things are returning an unable to post item to auction house, returning items to bag error, then the ability to try again is greyed out. So, please get this back up soon, the auction house is important to this game.

Just in case you have the same problem I had before:

If the AH is getting hit by a lot of traffic, there will be errors to mitigate the load so it's typically a matter of waiting a bit before attempting to post again.
