I've had a strange thing happen to a Drupal 6 site. All images are missing from the site. Looking at the Edit screen for a node shows that the ability to edit and upload an image for any node is missing.
Further checking the content types shows that under 'Manage Field' the 'Image' field [field_image_cache] has be removed for every content type.
As far as i can see all the correct modules are still enabled.
Anyone got any ideas?
