Well, I am baffled by it! Tried finding some births, but they don't appear unless 'all events' are specified. To test it,
I've searched for several marriages that I know are registered, for I bought the certs from the records office in Dublin, but a search for them produces no results.
I've tried using the widest search parameter, but then up come 4700 results, mostly from the USA, despite having 'Dublin, Ireland' selected!
I expect it is just teething problems......and that in a few days all will be well.
