Problem: I have an SD flash card (8 GB Kingston) and a MacBook Pro 13" (Late 2011 model). I also use external card reader time to time. This problem persisted on all the conditions. The error message was stating: The Finder can’t complete the operation because some data in “” can’t be read or written.

Not only PK of Page model rises and data are copypasted into new empty Page model instance. Those plugins are copied to. So mentioned plugins PK would change to 15 and 16 accordingly, assuming 14 is the latest plugin pk. New copied plugins will be linked to new page. Tha...
