This is by definition Gaslighting and Ad Hominem.
Is it a question?

The first rule of this site: Give us relevant informations about your question, about your problem.
Sometimes a screenshot gives more informations, sometimes an attached ODF type sample file gives more informations, sometimes a short video of your activity (in the application) gives more information.
.
The sentence “It not work!” can not give any information.
You was asked to upload a sample file in an another question of you, and you have not uploaded any sample file.
Then you’re a hypocrite because when the poster of that comment violated the rules you turned a blind eye too it.
That is clear from the fact that the rules also require too “Be civil.” and Not “post anything that a reasonable person would consider offensive, abusive, or hate speech.” which he did not do.

Unfortunately there is no such rule: “Do not be annoying, do not be non-responding member. Do not post/comment unusable dummy texts.”
We can not help you without relevant informations.
I didnt say or even imply there was so that’s a strawman fallacy.
The facts show you are here to denigrate me.
Here is a sample of your answers/comments:
“In the menu, click Insert - Page number and choose the position and type”
Didn’t work!
The page numbering works fine in the LibreOffice. You must show it us: what, how you did it in your problematic document.
