How to solve Issue with sub tables and WAMP

I have spend a full day fighting with subtables on a site where the local development is via WAMP

Finally noticed that by default WAMP used the MyISAM engine by default which does NOT support subtables.
Quick conversion of the tables to InnoDB was an instant fix

Suggest any WAMP users out here consider editing their MySQL & MariaDB my.ini files to read

; The default storage engine that will be used when create new tables
default-storage-engine=INNODB
