Error: "body must be at least 30 characters" when editing an answer

Question

I tried to edit an answer of someone else and got this message:

Oops! Your edit couldn't be submitted because:

• body must be at least 30 characters; you entered 19

---

It's this answer: https://superuser.com/a/112134/151741

I wanted to change

Ctrl + Alt + D

to

<kbd><kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>d</kbd></kbd>

---

Was the minimum character limit changed sometime? Would this mean that all answers that were created before can't be edited anymore?

Answer 1

As of May 1, the minimum character check was changed

My trivial thought here would be to strip tags and white-spaces prior to measuring post length.

so yes, you're running into that check. There's no reason you can't edit - see the same post that I've edited.
