Order on the Page when using portfolio

@greenwhite560: Hello there,
For that you will need to create a child theme and do a bit of customization. Let me know if you are familiar with child theme customization so that I can help you out otherwise I suggest you to hire a customizer to get it done.

Kind Regards,

@greenwhite560: Hello there,
Since you already have a child theme I will guide how to have the About page contain above the Portfolio section.

Go to => Child Theme Folder => create a new file header.php and add the code in this link and save.

Again,
Go to => Child Theme Folder => create a new file footer.php and add the code in this link and save.

This should make the portfolio section show up below the About Page content if you have the child theme activated.

Let me know if this works out!
Kind Regards,
Skandha
