The Glitch Market now uses the SDB/Tower API. I have removed that manual version(Marketplace) in favor of the new system which can be found by selecting a category on the left or using the search box at the top.
Auctions and Tower/SDB items are on the same list:
- Tower/SDB items have a 'Teleport' action
- Auctions have a 'Purchase' action

You can also search for your character name(or for someone else) to see all of the items you're selling. Here's me for example:
My Auctions
My Tower Items
edit: fixed it for you, Windborn ;)
