Conflict with attachment permissions

[sparklywater]

I'm using the following plugin code at hook location 'global_start' to make attachments work in PMs:

PHP Code:

if (THIS_SCRIPT == 'newattachment' AND $_REQUEST['type'] == 'pm')

{
 $threadid = -1;
    $vbulletin->userinfo['forumpermissions']['pm'] |= $vbulletin->bf_ugp_forumpermissions['canpostattachment'] + $vbulletin->bf_ugp_forumpermissions['canview'] + $vbulletin->bf_ugp_forumpermissions['canviewthreads'] + $vbulletin->bf_ugp_forumpermissions['canviewothers'] + $vbulletin->bf_ugp_forumpermissions['canreplyothers'] + $vbulletin->bf_ugp_forumpermissions['canreplyown'] + $vbulletin->bf_ugp_forumpermissions['canpostnew'];
    $foruminfo['allowposting'] = 1;
    $foruminfo['cancontainthreads'] = 1;
    $foruminfo['forumid'] = 'pm';
} 


Something in this code causes an error message when uploading attachments to thread posts: 'you don't have sufficient privileges / permissions to perform this action'. When the above plugin is disabled, there is no longer an error message on uploading attachments.
