The SQL History feature of my phpMyAdmin setup wasn’t working, the history table had been configured correctly as ‘pma_history’ but there was no data being written into that table when I ran queries and the SQL History tab of the query window just showed a blank.

Eventually I figured out that in order for the pma_history table to be populated I needed to set the QueryHistoryDB setting to true. So I did that and now SQL History is working!
