While trying to create a relationship to another view using the representative view drop down, I get this fatal error. I've tried installing the 7.x-3.x-dev version of views with the same error.
I have installed the 7.x-3.1 version of the Views module and the 7.10 of Dupal core.
I am relatively new to Drupal and tried to research the error on my own without success.
I have attached a screenshot of the error.
