I tried to debug this error. Finally, I have got the result.

To fix this error, just remove condition in hook forumdata_start. It's named xxxxx - Valid Fields

Original Code

		if ($vbulletin->options['apboupc_forum'])
		{
		$this->validfields['accessf_nb'] = array(TYPE_INT, REQ_NO);
		$this->validfields['accesst_nb'] = array(TYPE_INT, REQ_NO);
		$this->validfields['create_nb'] = array(TYPE_INT, REQ_NO);
		$this->validfields['reply_nb'] = array(TYPE_INT, REQ_NO);}

Replace :

		$this->validfields['accessf_nb'] = array(TYPE_INT, REQ_NO);
		$this->validfields['accesst_nb'] = array(TYPE_INT, REQ_NO);
		$this->validfields['create_nb'] = array(TYPE_INT, REQ_NO);
		$this->validfields['reply_nb'] = array(TYPE_INT, REQ_NO);

NOTE

1. If you remove "condition" by yourself, DONT forget "}"
2. The error occurs by one condition setted wrong place. I *guess* because of this, some *features* don't work correctly (as I checked up, the "viewing attachments" permission doesn't work)

Good luck all.
