SQL Error When Clicking all Users Online

[BlipHost]

When I click "28 Users Online" in the stats at the bottom of the forum, I get this SQL Error:

Database error in vBulletin 4.1.8:

Invalid SQL:

SELECT userid
, user.market_username_color,
user.market_username_glow, market_username_subscript
FROM session as session

WHERE session.lastactivity > 1322674527;

MySQL Error : Unknown column 'user.market_username_color' in 'field list'
Error Number : 1054

From the invalid query I'm guessing it's a problem with the market, is there any way to solve this without removing the plug-in? Some of my users have collected a large number of points, and I'm trying to solve this without taking those away.

It's possible that you could reinstall the mod and retain any points users have, but it depends on how the install code works. Or you could try just creating a column with that name in your user table.

You should ask questions about mods in the mod thread.
