Conversie de la phpBB2 la phpBB3 nesatisfacatoare

[aTenTie]

Dinu ma poti ajuta si pe mine cu conversia la forum, din phpbb2 la phpbb3 ?

Am incercat marge pana da eroarea asta :

General Error
SQL ERROR [ mysql4 ]

Lost connection to MySQL server during query [2013]

SQL

SELECT MAX(forum_id) AS max_forum_id FROM phpbb_forums
