I have just upgraded my drupal site from 6.5 to 6.6. For some content types I had created a fivestar field displaying my vote of the thing the content is about (movie, book). This field is not displayed and when I go to admin/content/types to manage the fields, there also no fivestar field displayed (field_vote). However, when I try to create a field with the same name (field_vote) I get the message that this field already exists.
I really don't know how to solve this problem and would appreciate any help. Please let me know if I should provide more information.
