The button to post a new auction is always gray and disabled for me. I've tried deleting the saved variables files, but with no luck. I'm not using any other auction addons or addons that modify tooltips. I've also tried using /aux clear post but that doesn't do anything for me. What should I do? Here's a list of all the addons I'm using

Are you using a higher starting price than buyout or a starting price of 0?
