I upgraded my Expression Engine installation to 2.7.3 (from 2.3.1). But after upgrading I get an error when trying to view the site.
Error Unable to load requested field type file: ft.relationship.php. Confirm the fieldtype file is located in the expressionengine/third_party/ directory
I can see that there is a expressionengine/fieldtypes/relationship/ft.relationship.php and if I go to the admin page I see a field type as being installed there (As “Relationships Version 1.0”).
Why is EE giving me an error at that point?
