Error at /api/title_search/ after the update to 0.7.45

edit

It seems that I get these errors every time someone uses the New search bar

(EXTERNAL IP): Internal Server Error: /api/title_search/

Bug?

EDIT:

I get the following by using the command: python manage.py migrate But I don't really know what that means

No fixtures found.

Edit 2 (After Update to 0.7.46):

I still get Error emails everytime a user searches on my askbot

I get the following by using the command: python manage.py migrate
