Los posts se redirigen a la página de inicio de XAMPP - Solución WordPress

Tengo un sitio WordPress que descargué desde producción y configuré localmente usando XAMPP. Cuando hago clic en cualquier post, me redirige a localhost/xampp en lugar de a la página del post. Mi archivo .htaccess es:

<IfModule mod_rewrite.c>
