WP Defender - Can't login after disabling file editor on multisite

I had WP Defender working on my multisite installation until trying to activate it on a separate site on my network. Now, I can't access my wp-admin backend and on the login page I cannot log in and get this line: define( 'DISALLOW_FILE_EDIT', true ); at the top of the page. My setup also includes the WP multi network plugin.
