Hello.
Coinciding with the latest system updates on nethserver 7 wordpress does not update the version and asks for a localhost connection in ftp. I did some tests and it seems to be a problem of permissions on php.
Thanks to those who can tell me how to solve the problem.
I assume you setup wordpress in a virtual host.
You may check permissions/ownership with ls -l /var/lib/nethserver/vhost/YOURVHOST and set apache as owner with chown -R apache: /var/lib/nethserver/vhost/YOURVHOST
You may try enable FTP and enter the credentials just for the update.
