I am using version 2.9.2 EE and Matrix 2.6.1 (both the latest versions of each software). Each time I try to publish a channel entry that has a Matrix fieldtype I am getting the following error message. Can anyone assist me with why I am getting this error.
A Database Error Occurred Error Number: 1054
Unknown column 'is_draft' in 'where clause'
SELECT row_id, col_id_1, col_id_2, col_id_3, col_id_4, col_id_5 FROM exp_matrix_data WHERE field_id = 105 AND entry_id = 937 AND is_draft = 0 ORDER BY row_order ASC
