A weird thing happens when I try to update this site. Maybe you can help me figure it out. It’s not the browser; it’s not the extensions; it’s not the operating system. WordPress help is useless — they tell me to just change the screen magnification using CTRL+. That doesn’t work.

When I’m working on a page, everything is fine and dandy:

Fonts are a normal, readable size.

But when I’m working on a post…

As you can see, the font is teeny-tiny. Literally nothing I’ve been able to do changes it. (It’s not like this on mobile, interestingly.) Oh, and I run two other WordPress websites, using the same exact browser; neither of them force me to compose posts with tiny text.

Do you have any thoughts on why this might be happening? Any ideas on what I could try? Any help would be appreciated.
