Since patch 4.0.1 broke most of the addons and especialy the ones that worked with the AH here are some temporal solutions until things get back to normal.
1. Working Auctioneer for 4.0.1: Link. Note that this is a BETA release. It works fine for me but some people might have problems with it.
2. Quick Auctions 3 is no longer maintained. The new addon is called Auction Profit Master and can be found here. It's the same as QA3 but with another name, so if you know how QA3 worked you'll have no trouble setting this addon. There is also the option to import your data from QA3. A how-to is available on the addons' site.
NOTE: as you may already know since 4.0.1 automatic posting and canceling is no longer possible. You MUST click every single post and cancel. For APM the two click macros you can make are:
Code:
/click AuctionProfitMasterPostButton
/click AuctionProfitMasterCancelButton
In addition there is what I believe a Blizz confirmation box that you must click to confirm. The click macro for this one is:
Code:
/click StaticPopup1Button1
Also if you need to know what's the name of a button use this run script:
Code:
/run local f = GetMouseFocus(); if f then DEFAULT_CHAT_FRAME:AddMessage(f:GetName()) end
So these are the 2 addons that I mostly use. I've heard that auctinator is updated for the new patch so just download it. Also note that some parts of Auctioneer aren't working (Enchantrix for example) so you'll have to wait for a stable release.
Anyway hope that'll help some people... you don't want to miss the glyph sales
