Hi there,
I noticed that I can't add new categories on a shop and guess it's probably a migration-error (Database).
After turning on the developer mode it says:
```
Unknown column 'displayfromsub' in 'field list'
INSERT INTO ps_category (nleft, nright, level_depth, active, display_from_sub, id_parent, id_shop_default, is_root_category, position, date_add, date_upd) VALUES ('0', '0', '3', '1', '1', '3', '1', '0', '0', '2018-06-23 11:51:48', '2018-06-23 11:51:48')```
```
Can somebody tell me which SQL command could fix this? :slightlysmilingface:
I found something like this for a similar problem concerning products:
```
ALTER TABLE ps_product ADD pack_stock_type int(11) UNSIGNED DEFAULT '3';
ALTER TABLE ps_product_shop ADD pack_stock_type int(11) UNSIGNED DEFAULT '3';
ALTER TABLE ps_pack ADD id_product_attribute_item int(10) UNSIGNED NOT NULL AFTER id_product_item;
ALTER TABLE ps_pack DROP PRIMARY KEY;
