I just updated an EE site from 2.4.0 to 2.7.2. Now going through and updating (many) plugins. I just updated Matrix from 2.4.3 to 2.5.8 and I get the error below while trying to click on Matrix in the Fieldtypes page in the CP. Any help would be awesome, thanks!

A Database Error Occurred

Duplicate column name 'is_draft'

ALTER TABLE `exp_matrix_data` ADD `is_draft` TINYINT(1) UNSIGNED DEFAULT '0'

See this post for info Matrix (2.5.8) update database error

Sounds like it is the same or similar problem. I had this once and the info there was enough to go into the database and sort out the issue.
