Broken/missing handler after reinstall

Question

my site recently got deleted by a possible hack. I uploaded backed up folders and the db but now my views are not showing. everything else works. i can't think of anything that changed, just uploaded a backup from a few days ago.

the fields are showing this in admin/build/views/edit/nameofview

Broken/missing handler: node_data_field_guru_photo > field_guru_photo_fid
Broken/missing handler: node > title
Broken/missing handler: views > nothing
Broken/missing handler: node_revisions > body
Broken/missing handler: node_data_field_guru_link > field_guru_link_url

I tried clearing cache

I rearanged the fields in views and updated them and got this error

Display "Defaults" uses fields but there are none defined for it or all are excluded.

Answer 1

Normally just clearing Drupal's cache would fix this but if not go into the 'Manage Fields' screen for the content type to which node_data_field_guru_photo, node_data_field_guru_link etc. are attached, make a temporary change (e.g. to the order of the fields) and save. That should force a refresh of the field cache and you should be on your way.
