Question Mark in boxes when using Chrome and Safari
Question marks in boxes started appearing in Chrome so I switched to Safari as my web browser but now it seems to be happening in Safari as well. I just updated my OS to BigSur and I am on a rather old iMac but this issue doesn't seem to be happening when I log into another user. I have cleared caches, restored fonts, gone into Safe Mode and nothing seems to be working.
