Diary page stays blank after adding food

Hi! I’ve been using Cronometer for years, it’s by far the best nutrition tracker around IMO

Recently a problem has occurred, I wonder if anyone has any ideas (I’m visiting the site on my desktop PC by the way, not the phone app.)

When I click on ‘ADD FOOD’ and add something to my day, the page stays blank but the daily total in ‘Energy History’ goes up. See screenshot:

I have tried using both Firefox and Microsoft Edge and the problem presents with both browsers. I have no idea what could be wrong, is it my computer? I hope someone can help

Thank you
