I upgraded to the latest version of playa (unsucessfully with Upgrader then manuallly). The module and field type are showing as 4.4.1 ok but I am getting php errors on all pages that contain playa fileds:
Error Number: 1054
Unknown column 'rel.parent_is_draft' in 'where clause'
SELECT DISTINCT(rel.child_entry_id) AS entry_id FROM exp_playa_relationships
rel WHERE rel.parent_entry_id = 5416 AND rel.parent_is_draft = 0 AND
rel.parent_field_id = 188 ORDER BY rel.rel_order
