Lost Catalog items

Hello everyone,

In the Back End Module -> Content -> Catalog I creata a catalog with 18 items.
In the "Edit multiple" option all 18 was checked and at all parent ID was change from 8 to 1-18 sorted for all items.
In result almost all items disappear.

System log show details as:
"A new version of record "artykuly.id=13" has been created (parent records: tl_catalog_types.id=18)"

Is there any way to reverse those change or the data is lost?:eek:

Affected version(s)
2.11.11

Make a backup of your database. Then search for the lost entries. If they exist then try to change the parent id back to 8 manually with your DB program e.g. phpMyAdmin.
