I have been using EE for years, without major issue. This year I had to switch some setting for Paypal, based on your instructions.
However – for some reason, LOTS of people are having probelms trying to register. Lots of failed transactions. Lots of people get spinning wheel and page stalls.
Any idea why this things could be happening? Goes beyond my technical expertise. We really need help, asap. Can we hire you to help?
