Describe your issue
After installation of wordpress in multisite with a dedicated subdomain and within a speficied directory ( /formation ), it is possible to see welcome but impossible to log into https://mysite/formation/wp-login.php, it fails and come back to portal.
I dig into the subjet and got the problem from nginx traces.
This is due to an update in latest companion auto update plugin ( - Revision 3329089: /companion-auto-update ) that removed cau_menloc and kept only cau_url but forgot that cau_menloc was still called in some place.
I managed to get it working only by setting this :
define( ‘AUTOMATIC_UPDATER_DISABLED’, true );
in /var/www/wordpress/wp-config.php
to deactivate autoupdate.
and restarted php fpm related service.
