I've encountered an odd bug, I'm not able to post auction listings for Arcane Elixirs. I have to launch the Blizzard UI for these items. When I select the item from the left window, nothing happens. No scan is done for current market prices, Aux seems to ignore or simply not recognize this item.

Probably corrupted savedvariables.
Get the newest version and try /aux clear post or /aux clear item cache and /run ReloadUI()

you can also use the shorter version of /run ReloadUI(), /rl

Thanks for the replies.

"/aux clear post" resolved the issue. Clear Item cache didn't help this particular issue. Uninstalling and reinstalling the addon also didn't help. Good to know in case I hit a similar issue again!
