i published a page after i made my new home page static and it didnt go on the home page
I’m guessing you made page A your static page, published page B, but still see page A as your home page.
That’s right. You made page A static. If you want to change it, edit page A directly, or change the static page to page B.
If you mean instead that you edited page A and published and there’s still no change, try force refreshing your browser by pressing ctrl/cmd + f5.
so if i have a static page my post wont go on there. is there a way to make a post to appear on different pages or categories of my choice
Create a blank posts page and define it as the posts page in Settings->Reading.
To create pages for different categories, you’ll have to create your own category templates.
