Got one little problem with the addon.
If I login to xenForo forum I then can post on WP, access WP admin, avatars are syncing.
My problem: If I click on an article on WP and try to login under the comment it directs me to my homepage. It won't redirect me to xenForo login.
Could you link to your website?
your domain.com/wp-login.php should redirect to xenForo login
and so should domain.com/wp-register.php
