    I am not to sure about your answer here.

    Looking at the plugins source code, it looks like the wp_redirect() is set to trigger on the WordPress login_head action, which is after WordPress has begun to output the HTML headers (hence triggering the error). Looking at the page source above the warning also agrees with this idea (the <html> and <head> tags are present, which should never happen when using wp_redirect())

    Here is the stack trace if it helps

    ( ! ) Warning: Cannot modify header information - headers already sent by (output started at /var/www/multisite-wordpress/wp-login.php:63) in /var/www/multisite-wordpress/wp-includes/pluggable.php on line 1174
