How do I fix the definer problem The user specified as a definer ('fred'@'192.168.0.%') does not exist
If you will recreate all your views this way (and will create all new ones with this syntax):

CREATE
SQL SECURITY INVOKER
    VIEW applications
AS     
SELECT id, product_id
FROM modules     WHERE item_type='application';


you will only need to make sure a user on another instance where you restored your database has grants to EXECUTE on your views and SELECT on tables involved.

Typical database user in a web application will have SELECT, INSERT, UPDATE, DELETE, EXECUTE until your web application creates database objects.

You do not need 'fred' to be a database user anywhere in this case even though this database user created this view on your web site.
