WotLK Bags bought from the Auction House are worthless.

[SXE2]

The same thing happens to me across three accounts and a dozen toons, any bag bought from the auction house when equipped gives no added storage. It'll sit in the slot but it gives no room. Disabling addons does nothing.

Did you actually try to open the bags you added or you are looking at your bacpack only? If that's not the problem try to relog after taking the bag from mailbox before using it.

[SXE2]

the bags don't open at all. They become soulbound but thats it. They become instantly worthless.

There are some problems with items from AH and guild bank but relogging before using them usually fixes it. Have you tried that?

[SXE2]

yes I have. It does nothing.

Going off-line for a half hour and logging back on the bags are now seen, very strange indeed.
