Hi When I tried to change/add or edit Order--? Status in PS 1.6.1.5 recently upgraded from PS 1.6.0.14 I got this error 

 

An error occurred while creating an object. order_state (Unknown column 'pdf_delivery' in 'field list')

 

now I can not add.edit order status 

 

Please check asap

 

Thanks

login to you cPanel and edit database using PhpMyAdmin
alter the table ps_order_state in your database. make sure there is a pdf_delivery column, if not then you have to create it.
I had the same issue with pdf_delivery and pdf_invoice so I had to create those 2 columns manually in the database and all resolved.

`pdf_delivery` tinyint(1) unsigned NOT NULL DEFAULT '0';
`pdf_invoice` tinyint(1) unsigned NOT NULL DEFAULT '0';
