Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource

[echo242372]

I am running PHP Nuke on my site, and everything was working good till today. I got the following error

Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /home/auctions/public_html/community/includes/sql_layer.php on line 301

Im new to phpnuke and this is a new error

Line 301 is

$row = mysql_fetch_row($res);

Thanks
Wayne

If you need more info let me know

[BlueMeteor]

paste your code....

$res=?

$res=mysql_query(?)

[echo242372]

Nevermind I was able to fix it. The problem was with my MySql database. So how it became corrupt

Best regards,
