Get the following error when clicking on Add-Ons/Fieldtypes/Matrix. Can anyone help? Thanks.
A Database Error Occurred Error Number: 1060
Duplicate column name 'var_id'
ALTER TABLE exp_matrix_cols ADD var_id INT(6) UNSIGNED AFTER field_id, ADD INDEX (var_id)
Line Number: 467
Updated EE to 2.6.1 and updated all Add-ons I have installed (left Matrix for last). Tried updating Matrix to 2.5.5 and now get the following error when trying to edit any entry:
A Database Error Occurred Error Number: 1054
Unknown column 'is_draft' in 'where clause'
SELECT row_id, col_id_21, col_id_22, col_id_28 FROM exp_matrix_data WHERE field_id = 55 AND entry_id = 75 AND is_draft = 0 ORDER BY row_order ASC
Line Number: 2912
Matrix 2.4.3 is working except that I can't add license key or update.
