I was updating a local EE install from EE 2.5.1 (20120529) to EE 2.7.1 (20130924). I've updated Matrix 2.4.1 to 2.5.8
When clicking on Matrix in the fieldtypes addon section i get the following error:
A Database Error Occurred
Error Number: 1060
Duplicate column name 'is_draft'
ALTER TABLE `exp_matrix_data` ADD `is_draft` TINYINT(1) UNSIGNED DEFAULT '0'
Filename: /third_party/matrix/ft.matrix.php
Line Number: 509
I also got a error for Playa, but that seemed to correct itself on refresh.
Any ideas what's up?
