Error creating new session (forum phpBB)

Salve,

da oggi ho un problema sul forum, risulta off-line e l'errore che dà è questo:

phpBB : Critical Error 

Error creating new session

DEBUG MODE

INSERT INTO phpbb_sessions (session_id, session_user_id, session_start, session_time, session_ip, session_page, session_logged_in, session_admin) VALUES ('d139942605fa347fd05dbb56e17ebadc', 2, 1157314990, 1157314990, '53b05d0f', 0, 1, 0)

Line : 200
File : sessions.php

Ho provato a riparare la tabella, ma da phpmyadmin non si riesce.

Ho trovato questo su phpBB.com, ma non sono sicura che sia il metodo adatto e soprattutto non vorrei fare danni a svuotare la tabella, vista la grandezza del db.

Create a fix.php file with the following: 
Code: 
<?php 
// Clear the sessions table, repairing if necessary 
define('IN_PHPBB', true); 
$phpbb_root_path = './'; 
include($phpbb_root_path . 'config.php'); 

// connect to the database server 
$db = mysql_connect($dbhost,$dbuser,$dbpasswd); 
if (!$db) die("Unable to connect to database!\n"); 

// select the PHPBB database 
mysql_select_db($dbname,$db); 

// Repair table, ignore errors 
$tablequery = "repair table ".$table_prefix."sessions"; 
mysql_query($tablequery,$db); 

// Clear table 
$tablequery = "truncate table ".$table_prefix."sessions"; 
mysql_query($tablequery,$db); 

echo "PHPBB sessions table truncated and repaired. You should now delete this file"; 
?> 


Upload the file to your board's root folder (the one with config.php) 

Run it by navigating to the file in your browser (ex. http://www.yoursite.com/phpBB2/fix.php) 

Delete the file after you see the "PHPBB sessions table truncated and repaired" message

Potete aiutarmi?
Grazie!
