I’m using this plugin (WP Remote Users Sync – WordPress plugin | WordPress.org, Repo: GitHub - froger-me/wp-remote-users-sync: Synchronise users across WordPress websites) and had the problem users couldn’t log into the remote site after registering with the “local” site. Problem was the password not getting passed/the hook of the plugin not fireing.
I managed to fix it by simple adding this line to the wp_password_hash function inside wp-password-bcrypt.php right before the return:
Could you please update the plugin with the additional line?
Thanks in advance, best wishes
