beta4 to beta5 errors

[dale09]

Please help. I am getting the following error on the content.php . Everything seem to be ok untill I tried modifying the categories. Here is the error I am getting:

Fatal error: Call to a member function can_view() on a non-object in /home/bob/public_html/packages/vbcms/content/article.php on line 661

Here is the above line of code:

$view->can_view_post = $post->can_view($user) ? 1 : 0;

Any help?
