[Solved] open in the same window

Hi @cihan,

Use the following hook code:

add_filter("wpdiscuz_author_link_attributes", function ($attrs) {
    $attrs["target"] = "_self";
    return $attrs;
});

Put the code in the WordPress active theme functions.php file.

Please delete all kinds of caches and check again. 

wpDiscuz also has a built-in caches system Please delete this cache as well. It's located in the Dashboard > wpDiscuz > Settings > General Settings tab.
