7-x-4.x-dev doesn't work on phpbb3

In the phpBB migration configuration, did you set the PHPDB Table Prefix to phpbb3_? What are the actual table names in your database?

I'm getting the same issue on mine with 2 phpbb forums to import, both on seperate databases, both installed phpbb3. THe prefix for them is phpbb_. But all I get when I run drush ms is this.

I'm using migrate 7.x-2.6-rc1+13-dev with phpbb2drupal 7.x-4.x-dev

.

Here are some changes I made in order to have 7-x-4.x-dev work with phpBB3:
First, I hade to tell it that phpBB version was 3 (it's internal detection mechanism did't work in my case). So
1) in phpbb2drupal.inc around line 32 (function __construct):

    parent::__construct($arguments);
	// BOF : force it to be version 3
    $this->arguments['phpbb_version'] = 3;
	// EOF
    $this->phpbbVersion = $this->arguments['phpbb_version'];

2) and around line 215 (function registerMigrations):

   if ($connection->schema()->tableExists($db_settings['db']['prefix'] .
    'attachments')) {
     $group_arguments['phpbb_version'] = 3;
   }
    else {
      $group_arguments['phpbb_version'] = 2;
    }
	// BOF : force it to be version 3
     $group_arguments['phpbb_version'] = 3;
	 // EOF

3) in file phpbb2drupal_core.inc around line 112 (PhpbbUserMigration/function query):

      $query->addField('u', 'user_jabber');
      // User type 2 is for anonymous and web crawlers
	  // BOF : changed user_type to group_id: 6=crawlers
//      $query->condition('user_type', 2, '<>');
      $query->condition('group_id', 6, '<>');
	  // EOF 

4) and finally around line 853 (PhpbbPostMigration/function query)

    // post_approved introduced in phpBB 3
    if ($this->phpbbVersion == 3) {
      $query->addField('p', 'post_approved');
      $query->condition('post_approved', 1);
	  // BOF : it should have be addField and not addFieldMapping
//      $this->addFieldMapping('p', 'post_subject');
//      $this->addFieldMapping('p', 'post_text');
//      $this->addFieldMapping('p', 'bbcode_uid');
      $query->addField('p', 'post_subject');
      $query->addField('p', 'post_text');
      $query->addField('p', 'bbcode_uid');
	  // EOF 

Be aware, this is a dirty solution, just for my needs. Hope it helps others in their migration or make one day this module work
