Ordering on the Series Archive Page

Please update the plugin to the latest version. I’ve added some filter hooks to make it easier for user to customize the plugin. In your case, paste the following code into your active theme’s functions.php. Be careful when editing the functions.php because if there’s an error in the code, it will break your website until you remove it via cpanel or FTP.

add_filter( 'wpeps_archive_page_post_order', 'prfx_archive_page_post_order');
function prfx_archive_page_post_order( $order ) {
    return $order = 'ASC';
}

add_filter( 'wpeps_archive_page_post_orderby', 'prfx_archive_page_post_orderby');
function prfx_archive_page_post_orderby( $orderby ) {
    return $orderby = 'date';
}

Let me know if it works.
