And this is what I have in core_moderators.perms:

It's not handling the data correctly, or this data is a different case.

Unfortunately I don't have the exact version of IPB because it was hosted and I no longer have access. The backup is all encoded PHP files and I am not aware of IPB storing its version in the database.

As far as I can tell, this is suggesting there's a moderator that could well be a super moderator, but also is a forum specific moderator, but if he's a forum specific moderator then he isn't actually assigned to moderate any forums - it's 0, rather than being an array of forum IDs.

With that in mind, it should just be a case of replacing this:
PHP:
$forumPerms = $this->_calculateModeratorPermissions($moderator);

foreach ($forumIds AS $forumId)
{
   $newNodeId = $this->_mapLookUp($nodeMap, $forumId);
   if (!$newNodeId)
   {
      continue;
   }

   $mod = array(
      'content_id' => $newNodeId,
      'user_id' => $newUserId,
      'moderator_permissions' => array('forum' => $forumPerms['forum'])
   );

   $model->importNodeModerator($forumId, $newUserId, $mod);

   $total++;
}
With:
PHP:
if ($forumIds && is_array($forumIds))
{
   $forumPerms = $this->_calculateModeratorPermissions($moderator);

   foreach ($forumIds AS $forumId)
   {
      $newNodeId = $this->_mapLookUp($nodeMap, $forumId);
      if (!$newNodeId)
      {
         continue;
      }

      $mod = array(
         'content_id' => $newNodeId,
         'user_id' => $newUserId,
         'moderator_permissions' => array('forum' => $forumPerms['forum'])
      );

      $model->importNodeModerator($forumId, $newUserId, $mod);

      $total++;
   }
}
else
{
   if (!$superMod)
   {
      continue;
   }
}
So we bail out of the forum specific stuff if there are no forums, and further bail out and skip that moderator completely if they are also not a super moderator.

Let me know if that helps.
