message_die(CRITICAL_ERROR, 'Error creating new session', '', __LINE__, __FILE__, $sql);

bunu bul

$error = TRUE;
if (SQL_LAYER == "mysql" || SQL_LAYER == "mysql4")
{
$sql_error = $db->sql_error($result);
if ($sql_error["code"] == 1114)
{
$result = $db->sql_query('SHOW TABLE STATUS LIKE "'.SESSIONS_TABLE.'"');
$row = $db->sql_fetchrow($result);
if ($row["Type"] == "HEAP" || $row["Engine"] == "MEMORY")
{
if ($row["Rows"] > 2500)
{
$delete_order = (SQL_LAYER=="mysql4") ? " ORDER BY session_time ASC" : "";
$db->sql_query("DELETE QUICK FROM ".SESSIONS_TABLE."$delete_order LIMIT 50");
}
else
{
$db->sql_query("ALTER TABLE ".SESSIONS_TABLE." MAX_ROWS=".($row["Rows"]+50));
}
if ($db->sql_query($sql))
{
$error = FALSE;
}
}
}
}
if ($error)
{
message_die(CRITICAL_ERROR, "Error creating new session", "", __LINE__, __FILE__, $sql);
}

bununla değiştirip dene.
