well the difference is in the way the queries are setup..
topposterspal.php uses
SELECT COUNT(*) as total,t1.B_PosterId,t2.U_Username
FROM {$config['tbprefix']}Posts AS t1,
{$config['tbprefix']}Users AS t2
WHERE t1.B_PosterId = t2.U_Number
AND t2.U_Number > 1
$dayssearchlimit
$limit
GROUP BY B_PosterId ORDER BY total DESC
LIMIT 0,$topposters
and always has
showflat.php for instance gets its value from
$query = "
SELECT t1.B_Number,t2.U_Username,t1.B_Posted,t1.B_IP,t1.B_Subject,t1.B_Body,t1.B_File,t1.B_Status,t1.B_Approved,t2.U_Picture,t1.B_Reged,t2.U_Title,t2.U_Color,t1.B_Icon,t1.B_Poll,t1.B_Parent,t2.U_Status,t2.U_Signature,t1.B_LastEdit,t1.B_LastEditBy,t2.U_Location,t2.U_TotalPosts,t2.U_Registered,t2.U_Rating,t2.U_Rates,t2.U_RealRating,t2.U_PicWidth,t2.U_PicHeight,t2.U_Number,t1.B_FileCounter,t1.B_AnonName,t1.B_ParentUser,t2.U_Birthday,t2.U_ShowBday,t1.B_AddSig
FROM {$config['tbprefix']}Posts AS t1,
{$config['tbprefix']}Users AS t2
WHERE t1.B_Main = $current
AND t1.B_PosterId = t2.U_Number
$Viewable
ORDER BY B_Number
$Limit
";
IF those two are throwing different things you need to do some TROUBLESHOOTING and look at why....
