"Content manager: broken/missing" After upgrading to Drupal 7, all the pictures of the items have disappeared.
In the View UI editor, I cannot add an image content and it says "Content manager: broken/missing".

Help?
"broken/missing" means that Views can't find the field. If you hover over the "broken/missing" link you can look at the address and get a hint of which field it's supposed to be. Once you know which field it is you can remove the broken handler and re-add it to the views output. If it's not available something has gone wrong with the field migration (I assume you did migrate the fields).
