Why can't I sell to the server anymore?

[thebowiejohn]

So yesterday I was making all sorts of good money, now I can't sell anything I get? I mean I can sell some things, if I go stand at spawn and click a sign about 500 times. Maybe re-add /sellhand back into the server. Also was wondering why I'm not able to sell ores?

Because people were making so much money, but I have no idea how to get money
