Cannot get plugin to work with Customized WordPress Theme

Hello,

I am using DonateNow WordPress Theme. However, I am really struggling to get any pagination to work with it. I’ve spoken with the creators of the theme I am using they said to make one change to one file template-blog.php. Your instructions say to make changes to two other files. I have attached copies of all of them. They still do not yield results. Can you assist?

see here for images of my files with proper modifications (they should all be clearly listed as to what is which):
