I had exactly this, clicked back and then proceed. Got stuck in this loop. But no joy. Was I refreshing the queue page , or my form as it kept giving me the prompt about form resubmit? Tried this for over an hour. Whilst still having other tabs trying for the reg page. Beyond gutted. It's been 25years on the trot for me, whilst some say it's time to step aside, I'm proud that I've spent over half my life supporting "the summertime Santa" that Mr Eavis is. It's disappointing that the system crashed like this and the payment page. There must be a better way to make this system cope with the demand. The queue page lol what is that really. The festival is my life, it changed me, and I so wish to be able to find a way back home, to my happy place with the happy people. Not giving up hope yet. Funk x
