我想將我個phpbb move去第2個host~應該點做?
我試個用phpbb內o個還原,then restore,但有以下既error:

Warning: open_basedir restriction in effect. File is in wrong directory in /usr/local/psa/home/vhosts/XXX.52-u.com/httpdocs/phpbb/admin/admin_db_utilities.php on line 938

Warning: fopen("/tmp/phpN7pw7H", "r") - Operation not permitted in /usr/local/psa/home/vhosts/XXX.52-u.com/httpdocs/phpbb/admin/admin_db_utilities.php on line 938
Warning: Supplied argument is not a valid File-Handle resource in /usr/local/psa/home/vhosts/XXX.52-u.com/httpdocs/phpbb/admin/admin_db_utilities.php on line 938

應該點做?
謝謝~
