Solved Subsequent pages in threads give an 500 Error

I think I have a wierd problem, maybe caused by the content of some posts. I have a thread that is set up identical to another thread. The initial page comes up, but of the 12 pages, only page 1, 8, 11 and 12 will show up. The rest show the error page attached below. I have looked in the Category table in the db and it is identical to other like categories. Anyone have a clue what could be causing this? Troubleshooting advice?

could you enable the kunena debug on configuration. Then you will get the real error message.

Here is one new error that popped up:

The error was detected in the Libraries.

Fatal Error: Call to a member function getEbayItemFromCache() on a non-object in libraries/kunena/bbcode/bbcode.php on line 192

// convert ebay item to embedded widget
$layout = KunenaLayout::factory('BBCode/eBay');

if ($layout->getPath())
{
this is line 192 $ebay = $bbcode->getEbayItemFromCache($content);

return (string) $layout
->set('content', $content)
->set('params', $params)
->set('naturalurl', $ebay->Item->ViewItemURLForNaturalSearch)
->set('pictureurl', $ebay->Item->PictureURL[0])
->set('status', $ebay->Item->ListingStatus)
->set('ack', $ebay->Ack)
->set('title', $ebay->Item->Title)
->setLayout(is_numeric($content) ? 'default' : 'search');
}
}

return $this->getEbayItemFromCache($itemid);
}

parse_str($params, $query);

Looks like the same issue in this thread too:
