Hi Barry. I just closed this issue out on the site yesterday. After a lot fo discussion with the client, they weren;t keen at all on remaining with that system – either as a beta of 3.0 or trying to correct something that was causing so much issue for them.
Instead, we have gone for another solution (The Events Organiser) which suits the requirements of the client very well.
Thanks for your time on this. Hopefully it’s an issue you can clear up with WPEngine, as I have an increasing number of sites there.
Best wishes, Andrew.
