The Black King is not shown in the diagram

[cuvno]

1.)
The Black King is not shown in "Chess diagram". (Not "Chess game")
for example...
[fen]4k3/8/8/8/8/8/8/4K3 w - - 0 1[/fen]
Is my writing wrong?

2.)
I want to show only the White queen in "Chess diagram". (Not "Chess game")
for example...
[fen]8/8/8/8/3Q4/8/8/8 w - - 0 1[/fen]
Is that possible? How should I write it?

I am using WordPress Classic Editor.
The WordPress version is 6.6.1. (Probably the latest.)

No problem on my side:

Thank you for checking.
I'll try to find the cause myself.
And thank you for providing a great plugin. My site wouldn't work without it.

What is the address of your website, and do you have a example of a public page showing these diagrams?
