I really need your help, I'm a beginner on Wordpress and although I have some sense of logic, I'm still very lazy in programming.

I did a wordpress installation inside a folder called blog, getting www.mysite.com/blog, and for the site to be accessed directly from the root, I copied the index.php file and informed the new path, to access only by www.meusite.com

The site loads normally but the paging of the posts displayed on the error home page:

For example, on the button for page 2, the mysite.com/page/2/ link appears, but when it is clicked, it only reloads the page.

If I type directly in the browser myite.com/blog/page/2/ there the other pages work with pagination, except if you click the first page, which returns to the root of the site.

Fucking in the code, I discovered the file responsible for the pagination and tried to put the full address where it pulls the url:

Original

$text = str_replace( $format, number_format_i18n( $page ), $raw_text );
    return "<a href='" . esc_url( $this->get_url( $page ) ) . "'>$text</a>";
}

Changed

$text = str_replace( $format, number_format_i18n( $page ), $raw_text );
    return "<a href='/blog" . esc_url( $this->get_url( $page ) ) . "'>$text</a>";
}

It worked only on the first page you clicked, because after the page is clicked, when it reloads it returns link on the link other pages ...

Has anyone ever had this or do you have any idea how to fix this error?

Below is the complete code for this file:
