Hello, thank you for getting back to me 

I tried clearing cookies/browser history etc already and that didn’t work. 

I have tried to do it on my iPhone, my iPad and my laptop and none seem to work. I have the same things come up on both iPhone and iPad. On my laptop I just get a blank screen when I click run.

it was working fine last month. I have been using it for nearly 2 years now and never had this problem before
