New version of PHPMyAdmin has stopped me being able to edit data

Question

PHPMyAdmin has just been upgraded by my server admin to v4.0.4.2.

Now I am unable to edit rows in the following table:

CREATE TABLE IF NOT EXISTS `pr         


        

Answer 1

Without unique key, there is no way to differentiate between two same records which can exists. Therefore phpMyAdmin can not safely edit the table - you have no clue which of these would end up edited. Do you really want to have duplicate records in this table?
