Pagination not working properly

Hello,

I’ve been trying to setup a wordpress website on my server, but I keep on encountering the same problem.

I uploaded my wordpress website under a /wp folder -> https://dev.example.com/wp

But whenever I try to use the pagination on the home page, the links of the pagination are :
– https://dev.example.com/page/2
instead of
– https://dev.example.com/wp/page/2

(plus the pagination is working on category pages such as https://dev.example.com/wp/category/mycat/page/2/

Here is my query :

if ( get_query_var('paged') ) {
    $paged = get_query_var('paged');
} else if ( get_query_var('page') ) {
    $paged = get_query_var('page');
} else {
    $paged = 1;
}
        $args = array(
            'posts_per_page' => 6,
            'orderby' => 'post_date',
            'post_type' => 'post',
            'order' => 'DESC',
            'post_status' => 'publish',
            'paged' => $paged,
            'post__not_in' => $ids,
            'suppress_filters' => true
        );

 $post_query = new WP_Query($args);

I thought it could have come from my .htaccess, so here it is :

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wp/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wp/index.php [L]
</IfModule>

I don’t know if I should have a specific .htaccess at my root?

Thank you.
