adopt page error

[GuardiansWish]

So I created a new pet (a simple testing pet, 1 level, nothing special). I went to the adopting page (http://chibifurs.com/adopts/adopt) to adopt the pet, I received this error:

Fatal error: Call to a member function count() on a non-object in /home/chibifur/public_html/adopts/classes/abstract/abstract_guicontainer.php on line 392

we are supposed to be opening the site again tomorrow and need some help figuring this out <3

Well the page will throw a fatal error message if you have no available adoptable in adoption center. To fix this problem, download the attachment here:
