Da phpBB3 a vB4.0.2

I gruppi importati non hanno nessun diritto. Per risolvere il problema, spostare gli utenti ai gruppi "regolari" rimuovere i gruppi importati successivamente.

ragazzi ma una guida di impex????

$impexconfig['target']['server'] = 'localhost';
$impexconfig['target']['user'] = 'username';
$impexconfig['target']['password'] = 'password';
$impexconfig['target']['database'] = 'vbulletin_forum';
$impexconfig['target']['tableprefix'] = '';

# If the system that is being imported from uses a database,
# enter the details for it here and set 'sourceexists' to true.
# If the source data is NOT stored in a database, set 'sourceexists' to false

$impexconfig['sourceexists'] = true;

# SOURCE - The source is the old forum database (where the data is coming from)

# mysql / mssql

# DUPLICATE CHECKING
# Where unique import id's are available ImpEx can check for duplicates with some
# Tier2 systems this will need to be set to false.
